1. hepdanaviruses DON'T have their own RNA polymerase, but uses their host's enzymes for this. 2. they DON'T have double stranded DNA, but they have a so-called 'partially double stranded' DNA because part of it is single stranded. 3. Their DNA is NOT coiled, they only have a few kilobase pairs of DNA material (3-4 kb) but they do use overlapping genes (meaning that the genetic code of one gene can have base pairs of another gene's code). So after 3 minutes in i doubted everything you said...

got fed up when u just mentioned about RNA polymerase instead of DNA polymerase. Please give a valid and authentic answer to the viewers.

HBV contains DNA polymerase firstly n secondly HBV have double stranded circular (incomplete) DNA rather than supercoiled one.correct me if m wrong.thanks

Exactly, DNA is converted to supercoiled dsDNA.

dearest shomu, why didn't you mention the incompleteness of positive strand of DNA, thanks a lot for the tutorials

Dear Shomu, are there viruses that work in the same way that have already been cured?

It has relaxed circular DNA .ccDNA develops once it enters hepatocytes nucleus

GUYS PLEASE DON’T TRUST THIS VIDEO he’s inventing the full process. Those are few mistakes he’s making: Once inside the nucleus: 1 the partially dsDNA is repaired to dsDNA and 2 the dna is transcribed by cellular dna Pol not viral dna Pol. Maybe the one you think it is the viral dna Pol is protein X that has a transactivation activity. Than the process of revers tanscriptased happens not inside the nucleus but INSIDE the viral core which find itself in the Cytoplasm. I mean you invented the process... before making a video please read a book: Jawetz or Murray Microbiology could be just fine. If those books are mistaking thank at least publish the refs.

camilla semenzato ....I came here just to understand this little point and he made me more confuse.

@ahmedelsakka9548 4 жыл бұрын

You are right .. but where the reverse transcriptase works on mRNA ?? in nucleus or cytoplasm And is the reverse transcriptase already carried in the virus or it will be encoded by viral genome ??

Was actually helpful, I just died when he sneezed and the video went silent for like a minute - I assumed he was wiping his nose, hilarious! I'm just a bit unclear about the mechanism for the circularisation, like how does it actually occur.
