My teacher uses your videos in lessons, my exam is tomorrow and im stressing so hard because she hasnt taught us well. Our Unuversity class has a class average of 53. She never incorperates the textbook in her lessons . She only uses bland power points and never goes into the point. Our class poor performance isnt due to us. Its because her tests are extremely difficult and believe me I studied my ass off for all her tests. I spent at least 9 hours studying for our genetics unit test and ended up doing mediocre . She also decides to give us a unit test the week before exams and didnt even review for the exam. She is by far the worst teacher i have ever had. She is the reason I wont be in honour roll. She squeezed in a whole unit two weeks befor the exam. Who ever is reading this thank you for listening.. needed to vent.

I'm just here because Molecular Cellular Biology is soooo interesting - especially Abiogenesis, 'Chemical Evolution', and Intracellular Machinery. And I didn't even study basic inorganic chemistry in Community College. (My Associate Degrees were in Business, Accounting, and Computer Science). But I find that seeking knowledge is enthralling now, while getting High Honors back then was primarily a function of educating myself regardless of Professor or Teaching Method. Like the Nazi Lady in 'Indiana Jones and the Crystal Skulls' said: "I vant to know!" Anyway, it sucks they made you do Biology as a completion elective when all you are interested in is Psychology. And, totally agree with you that (even though I had some brilliant Professors), many were also idiots. I remember a Statistics 'Professor' who raced so hard writing out the lecture on the board, and started erasing it at the end as I was the last one to leave still trying frantically to copy it all down. Apparently, she also had gained the illustrious position of the Dean of the Mathematics Faculty. Yet, according to rumor, past years' students had rebelled and tried to get her thrown out!

@Sunsidefury 11 жыл бұрын

If you have the 5' end, hanging off at the end (not bonded), the part that actually binds the next nucleotide is where the 3' carbon of the same nucleotide is: 5' (nucleotide 1) 3' (still nucleotide 1 just other side of the deoxyribose sugar) | (bond) 5' (nucleotide 2) 3' (still nucleotide 2) | (next bond attaches here) As you can see the 5' end is on top and the 3' is on the bottom so the flow is 5'-3' but if you'd want to continue on, you'd need to add to the 3' end of nucleotide 2.

OK. Mutated part of the DNA ladder is replaced by the corresponding backup in ideal situation. How to be sure that mutated part will not be treated as norm, discarding and overwriting healthy backup, essentially permanently cementing the change in DNA?

Hi I am a bit confused on why DNA is called a "molecule"?. I can see a nucleotide being a molecule made up of very specific component molecules(phosphates, sugars, bases) in a specific form/arrangement. But DNA is an entity made of one or more of such building blocks(nucleotides). In other words, a DNA can have 1 rung (taking the ladder analogy), or trillion rungs. As you said, proteins are made of amino acids, and carbohydrates are made of sugar molecules, but you dont call proteins or carbohydrates as a molecule? So how is DNA a molecule? Am I missing something, or is it just semantics that is confusing me? Asides, your videos are really great, and thought provoking!

@FrozenTill2013 8 жыл бұрын

+Satya Rao Proteins and RNA could both be called molecules also, you're just getting confused in the semantics like you mentioned. Anything that's covalently bonded is called a molecule in a general sense, like peptide bonds or phosphodiester bonds

Since there is no hydrogen on phosphate group (PO4) how it can donate H ions to be called as (nucleic) acid. Secondly there is Oxygen molecule on deoxyribose sugar then why its called deoxy ? Why say OH radical is absent ?
