    "After uncoating of the virus, unidentified cellular enzymes convert the partially double-stranded DNA to covalent closed circular DNA that can be detected in the nucleus"
    From Jawetz Microbiology
    At 3:30 you say the repair takes place with the help of 'reverse transcriptase of the virus'...

      My health was horrible because I was diagnosed with Hepatitis B and I felt like there was no hope for my health because I was told there was no cure. But today I am here to let everyone know that there is a herbal medicine to cure Hepatitis B and other diseases because I was able to get rid of my Hepatitis B with the help of Dr.Auchi on RUclips channel herbal remedies..ruclips.net/channel/UC6tA16t1IlKx1bY93lc2rcg 🌹🌹

    1. Partially dsDNA converted to fully dsDNA by viral DNA polymerase
    2. Transcription using cellular machinery to form RNA (translated to viral proteins and partial dsDNA again!)
    3. Gets converted to partial dsDNA again by reverse transcriptase!
    Note viral DNA polymerase has two functions: conversion of partial dsDNA to full dsDNA and and reverse transcriptase (conversation of RNA to partial dsDNA again).

      That last work of converting a full dsDNA to partial dsDNA is now done by RNAse'H enzyme

    This cycle is incomplete and is valid only for first progeny of HBV. For second and subsequent progeny, progeny DNA synthesised from mRNA transcribed from viral circular dsDNA undergoes transcription to form progeny mRNA which is synthesised into genomic DNA. This genomic DNA integrates with the host and transcribes genomic mRNA to synthesise more progeny.
    Correct me if I am wrong.

    Nicely explained! I have a question regarding UW. Is it ok to do all UW questions during PRE-dedicated period? Or a certain percentage of UW questions should be left unused for dedicated period?? Thanks in advance!!

    • @acingmedicine
      @acingmedicine  4 года назад +1

      I’d suggest you do some in dedicated since your outlook would be different by then. But even if you finished it you still have the reset option
