The best part about his style of teaching is the storyline and narrative visuals. He doesn’t just point out and explain, he makes you UNDERSTAND the whole biological process regardless how abstract the concept is. He paints a picture that you will remember, and that in itself, is a true talent. 💯

I need his enthusiasm for my studies!!!! His passion for Medical Science is contagious and so his happiness while explaining concepts. How even the most complex of topics start appearing lucid. Such a kind soul... I owe him so much !!

I know this is an old video but I really want to say thanks. I'm literally going to cry omg I always hated biochemistry in my veterinary medicine studies but I finally got it and your video is so detailed yet so understandable. I searched forever to find videos that explain this topic/ Genetics and include all the information they test us on. Your channel is like a gift from god. Especially with the clinical references omg it's so helpful to connect the dots. I`m so happy, sitting in my room crying happy tears. I never knew biochemistry could be enjoyable but watching you explain everything is so much fun. Asking "me" questions and knowing the answers repeading the stuff by watching and being able to remember it omg you saved me. Lots of love from Germany

I'm at a point where I watch your videos for fun. you make learning so easy and fun, thank you so much!

I'm a dentist. Passed my boards years ago and am fully licensed but... man, I feel like a student all over again! This is a phenomenal presentation and a great review! I hope you consider becoming a university professor one day. (I like studying USMLE material to make me a better overall provider - in case you may wonder why a dentist would be on this video).

Hi, I am a med school student and I hadn't been able to grasp the whole concept for my bioscience class until now. Just wanted to thank you for helping me prepare for my final exam which is coming soon!

I was starting to doubt why i study biology because having to study off of 1000 page books was just miserable and made me feel stupid for not remembering a thing afterwards. Your videos have been extremely helpful making me understand and memorize the subject better! Thank you so much for reigniting my passion for science and reminding how interesting and cool molecular biology can be!!

1st year med student here and a big thank you for all the effort around embryology biochemistry and even in phisyology you are really making it easier and I am really thankful Much love and respect your nerd from egypt

When someone explains something with so much passion 28:00 it makes the argument so much more interesting and easier to understand.

This professor has NO IDEA I’m one of his students! I’m here for the unmatched enthusiasm! The drawings and great explanations. Can’t wait to take a test tomorrow. 🤣 Dunno how he makes it a whole hour without half times or time outs. 😊 thankful I can pause and re-play explanations over and over until I get it!

when u say(support by commenting on the comment section) my mind becomes confused,thinking about which words u deserved. we really appreciate it,thanks ♡

Been super deep into your Neurology playlist these days. was watching your "Descending Tracts: Overview" right now. saw u uploaded this one. came here just to say thank you. words can't describe how much thankful i am.

You've saved me throughout my nursing school and now again during MCAT studying!!! WOW CAN'T SAY THANK YOU ENOUGH!!!! YOU AND YOUR TEAM ARE AWESOME HUMANSSSS!

This is the best lecture ever i had heard since my 18 years right now.....Thankyou man!♥️

I can't call you a lecturer anymore, you are a super lecturer!. Thank you for your incredible explanations.

As a genetic engineering major I've been studying this particular subject as a core course part. Each year it progresses on to the more advanced aspects. I can vouch that this hour long video perfectly encapsulates 3 year long course progression. Well done.

This video is just amazing !!!! U explained a whole lecture taken in 4 hours in just an hour and so smoothly!! We can’t thank u enough and literally ur the one who is helping me pass my medical years !!! Thanks a lot !!

You have the ability to make things so simple and easy to grasp. All my years of schooling and professors and I still go to you when I need a concept broken down. Thank you.

Dont know how to be thankful for u..your classes are very much helpfull for my pg exams.The way of teaching itself made the entire concept remind in the mind .and does not required any extra time for studying.your explanation made me to understand with complete process and does not requires any extra time for preparation.Like an artist paints a picture .for me your a gift from god.Thankyou so much sir for helping to complete my postgraduate so smoothly.🙏🙏 Love from India

This video is incredibly good. I'm a senior high school student from Spain, and I have my bio test next week. I've been looking for videos that explain the DNA replication properly and easily, and I hadn't found any in my language. But THIS ONE. Perfect explanation, super easy to understand every single step. Thank you so much Professor Murphy!

JUST WOW! I'm a clinical laboratory scientist and I’ve been struggling with biology since ever! before I find this channel, I find biology sooo hard to understand. now I even enjoying it! Thanks, Zach You’re a great teacher💯And this channel is incredible 🤩

The dedication! The excellent diagrams! The personality!!! I am blown away that this is free THANK YOU from the bottom of my heart for helping me graduate

OH GOd, literally the best translation EVER, now it's so easy to understand and connect all of that information. It blows my mind that this is actually possible to understand and memorise.

Hi ,I just want to thank you for all the lectures in science.I am a retired nurse and I have been reviewing and learning again by watching your videos.I always enjoy learning so I make watching your videos part of my daily schedule.I love the drawings and your passion in explaining the difficult parts.More power to you.

Thank you very much you have explained these complicated concepts in a clear and concise manner my college Biology Professors cannot explain in a million years. I feel a sense of relief when you explain scientific concepts. Thank you very much.

4 months of my biochemistry professors lectures vs a few hours of zachs videos, and I see a big difference in my learning. thank you Zach for making learning so easy. I've said it before and ill say it again if I die and you want my organs pls take them.

I have never seen anyone explaining like you You are simply extraordinary I don't have words to say how good your teaching is. The way how u make us understand the concept is amazing.

I swear to god that I’ve never seen someone explain this better than u I will advise my doctor to watch ur videos 😂😂

literally i watch the whole video without getting board for a second, Thank you!!

This came at the perfect time! I'm in Microbiology all summer and this has helped so much! Thanks again for another great lecture!

You are a brilliant lector and teacher! Even with not advanced english I understand such a difficult material. All because of your talent. Thank you a lot for this work!

I'm in no particular need to know this, but goodness! Your lectures make any topic so fascinating and understandable. Thank you.

Wish my High School teacher was like him (back in the day)

Waaaaaah!!!! Finally FIIINAALLLYYY GENETICS! 🥺🥺🥺🥺🥺 I was waiting for this looong time ago...i am really happy and waiting for transcription, and translation 🙏🙏

I am an IMAT student, and I hated biochemistry but brother... You are amazing and you deserve a lot of followers.

Look, I want to thank you to the infinity; you have managed to make me love medicine with your fantastic explanations of things. You are a wonderful lecturer keep going and remember that there are many people who appreciate what you are doing. I'm a medical student by the way

I am so grateful for how you broke this whole concept down! Thank you and I hope you keep making more helpful videos!

You are the GOAT bro. I also help students in A&P and physics and I have learned a lot from you and your "easy-to-comprehend" teaching style. I bought a shirt to bring you in some extra cash. I will buy many more in the future if you can do different materials! You help a lot of people, so thank you for all your hard work!

I have been glued to absorbing your teaching. Thank you for providing the world with education. Your lectures are so clear that you kept my attention span. Where have you been all my life? I don't know if it's the passion radiating from the screen, the deep breaths you take before diving in, the multi colors on the whiteboard, your already prepared drawing, me following your lead when you sit down, or the fact that you stay on point. I appreciate this very much.

I've never seen in my life such a perfect simplification, I'm delightful...thank you so much

im a med student and these genetics lectures save my life while studying! keep up the good work!

I appreciate this channel as a molecular biology and genetics student. thank you so muchhhh

Came here for my MCAT prep and coming back today for my med school science exams. Keep it up!!

I've no words, I can't thank you enough. You came as a blessing. I'm crying in happiness finally I understood everything.

The topics with which I was struggling , u clear those very smoothly.. Thnk you so much Zach ❤️

I love love love love your videos, my friend. I have watched them and learned from them since my high school days. I am doing my Master's in Zoology currently, and I still watch your videos for a lot of my topics. You remind me why I love Biology and I hope you continue to post more. Great work.🥰🥰 I would love to meet you someday in person🤩🤩

Currently mid video and I just had to stop and comment...WOW! My brain is on fire! Not only are you delivering content, but you're making it make sense in such a simple way. So happy I found your channel!!

I absolutely love all these lectures, you are seriously the best teacher that I have ever had. I am in NP school and you are teaching me just about everything. I have developed a habit where I read the material watch your video over and over than go back and read again, and everything makes complete sense. Thank you sooooo much please never stop posting !!!!!!!!!!!!!!

turning off ad blocker for your videos. massive props

I will be buying your merchandise for real way better than watch slids

What a freaking life safer you are. Revision of biochemistry became a breeze once I found your channel. You're a real one.

legit a lifesaver! I am studying for a final and could not find a video that explained this concept step by step! this was so helpful and he broke it up step by step! thank u so much!!

i just love your each and every lecture the way you teach

You inspire me! I watched your videos and made me think about taking up masters. I’m a clinical laboratory scientist. Thank youu ❤️

As a physician, I am almost not clear about molecular, biology and things like that but since I have known your channel, submerging in your lectures, I was able to understand that challenge knowledge. Thanks very much for your dedication. Love from Vietnamese fan

wasted several hours on long videos without understanding the basics of the subject, but in an hour you made me understand the subject and love it. Thank you so much.

I'm in high school and we take advanced biology this year and your videos are so simple and easy to understand thank you sooo much !!

It's really hard to find the right words to say, bcz thank you is really an understatement.

In India we have lots of exams, I really wished to have a teacher like you. I really appreciate your teaching. Thank you so much. Stay blessed.

The way he smiles😄😄 and the way he proceeds in a story manner is just a magic 🎉

Why aren't you the most popular chanell on youtube xD? I asked people, which are learning biology in the high-school do they know you. They didn't xD. But some of the med students in Poland said that u helped them to pass the exam :D. We are super thankful

Love the videos! I´ve been struggling to understand this theme, but after I have watched this video, It all made much more sense. Thank u for being so good at learning and you make biology actually fun and understandeable. Keep up the work! :)

I dont know how u garner such intricate understanding of all this. Biochem goes whoosh above my head! But you! You make things easy for my tiny brain! Thanks a lot. Really grateful!

His way of teaching leaves no choice other than to understand that too as good as a fairy tale and that we can never ever forget.Thanks a Ton

This is cool and I am learning so much about cell biology thank you!

Regarding telomeres, presumably after telomerase has extended the parental lagging strand, the DNA polymerase will extend the incompletely finished daughter strand to match the extended parental strand. I was confused about that but otherwise great overview!

I just wanted to put out this - there's like tons of people on youtube trying to explai things easy but when I look at my notebook its the same as always! just a mess! BUT! when I draw with Zack, it just makes sense! Thank you so much for all the helP!

Best lecture on DNA replication ever. Thank you, Prof. Murphy. College professors leave no stone unturned to make this topic a complicated one.

On spring break this week and start DNA next week.

I’ll become best doctor because of u man

I cant believe that I pay over 30k a year to a university and I learn 100x better from you. You explain these topics so much better than any professor that I've had my entire time in college.

Ninja nerd 💙 I finally managed to watch a one hour plus educational video without dozing off 😁 am now a certified ninja 💜 thanks ninja nerd 😘

I do have a question : Doesn't Helicase work on both ends so wouldn't the leading strand will also have few nucleotides left like the lagging strand?

So grateful for you guys. you are unarguably amazing. if i ever get anywhere close to your level of knowledge, enthusiasm and sheer awesomeness i'll be grateful. carry on self actualising!!!

I like your style, your way of teaching, and how you relate basic scientific facts and processes to medicine.Time literally flies when I am watching your videos!!!

Congratulations, Zach for 3 million subscribers ❤

Hi thank you so much for this lecture! There is one thing I wanted to clarify, I hope I can ask about it here. So when you were talking about the leading and lagging strand I just wanted to clarify that the Okazaki fragments are in fact present in both top and bottom parental strand. Is this correct? What I understood from the video is that the leading strands are found in the top parental strand while lagging strands are found in the bottom parental strand as the synthesis occurs 5' to 3'. But the replication is bi-directional so this means Okazaki fragments must be present in both parental strands right? Am I correct in assuming that when you were talking about the leading and the lagging strands, you were just looking at one direction of replication for simplicity sake to explain the concept? I hope what I said makes sense. I just wanted to make sure my thought process isn't wrong. Thank you!

Thank you so much for your video. But I still have a small doubt, can you tell the difference between DNA polymerase 123 and DNA polymerase alpha beta gamma delta and Epsilon? Are the number polymerases same as the polymerase with Greek letters? According to what I read from a book, it says that the numbered polymerases are for replication in bacterial cell but the Greek lettered polymerases Are for replication in human cells. Can you please clear this doubt?

Is there anyone else who’s better than this Ninja ? I feel like a nerd now. Once I get my first job I will subscribe to be your patron. I love you

I am a first-year pharmacist student and I currently read biochemistry, I hated it until I found you. My literature is in English but we have to learn everything in our native language. So the teacher lectures in Swedish. But they are so bad at explaining so I was close to quitting because I didn't understand anything. Even though you speak English, it is so much easier for me to understand you rather than my teachers. I am so grateful for these videos!

Another error found. The terms, “leading,” and “lagging,” strands apply to the newly synthesized DNA strands, not the parent strands.

I wish you're my prof instead

At this point I don't know how many videos I have watched. This one is by far blowing my mind the most and is absolutely getting me through my chiropractic basic science material. I utilize your lectures every week to better understand the concepts as I struggle with this type information. Thank you so much for what you do. Proud to be a ninja nerd :,)

You are a true hero I really can’t thank u enough I don’t like biology but I’m a med student and i really started liking it thanks to your videos, your passion when u talk is truly inspiring

Free free Palestine

Ok, you've made some seriously epic videos in the past Zak but this....... 🤯🤯🤯🤩 just next level and I didn't think there could possibly be a next level. You're making your own levels now. Thank you!

Omg !!!! Thank you !!!!! Finally someone broke it down in a way I can understand!!!

You are incredible! Thank you so much for sharing your brilliance with us! You are saving a lot of us!

I really really enjoyed your lesson. I've always believed that teaching is an art and not everyone is good at it but you are clearly a master! thank you for making this series.

the way you explain these concepts is making me be even more passionate about this field! thaaank you! I think most of the doctors of the next generations will have to thank you for eternity :)))))))))

Now I understand this mechanism rightly! thank you so much Zach.

You are the best teacher ever♥️

One of the best videos I have seen and understood by far the most, Thank you very much🙏

I must tell Ninja Nerd is a born teacher. I feel GOD presence in him. He is unique. I expect him for the whole decades to come for the mankind. this type of man is rare. what a devotion to teaching.

One of the best vdos ever. I don’t know why but a few points of dna replication were the ones i could never understand no matter where i read them from or what vid i watched. This is the first time I understood them all thanks to you! I have a feeling that I wont need to study this topic ever again thats how amazingly you taught it!

I don’t know how you don’t have more followers. Your videos are ALWAYS on point & clear. You have helped me 10 folds. Thank you!!

i am so grateful for your videos, for the first time ever i have understood replication for real and i am in my masters.

ooh, i cant express the love i have for your videos. for sure am just in first year of medicine but your videos have really helped me to understand most of the medical course units. i thank you very much ninja Nerd.

How do I triple like your videos? My God I’m really enjoying them. Please keep up the great work. 👍

Whenever I watch your vedios learning totally becomes fun and you make everything seems so simple that I just wanna watch all of your vedios at once and gain everything.♥️
