Q

How HIV works part 2

A
  1. Integration: DNA HIV enters the nucleus and the intergrase enzyme the cells DNA (real) and inserts the HIV DNA
    5: Transcription and translation: The enzyme RNA polymerase makes RNA copies of DNA, HIV RNA is either inserted into new virus particles or processed and translated into HIV protein
  2. Assembly: The long protein chains are cut into individual proteins by the enzyme HIV protease. A new virus is assembled with these proteins and HIV RNA
  3. Release: The new virus particle is released from the host cell taking with it part of the cell’s membrane and capable of infecting other cells
