HIV

• Here is the HIV structure

  
• Replication of HIV


  1. HIV enters the bloodstream

  2. Attachment protein attaches to a receptor molecule on the cell membrane of the host TH cell

  3. Capsid is released into the cell, where it uncoats and releases the RNA into the cell's cytoplasm

  4. Reverse transcriptase is used to make a complementary strand of DNA from the viral RNA template

  5. Double stranded DNA is made and inserted into the human DNA

  6. Host cell enzymes used to make viral proteins from the viral DNA found within the human DNA

  7. Viral proteins assembled into new viruses, which bud from the cell and go on to infect other cells
• HIV can be transmitted through sexual intercourse, blood transfusion, through breast milk or across the placenta to an unborn baby.
• When there is a shortage of T-helper cells in HIV replication, B cells are not activated and no antibodies are produced.nThis causes HIV to develope into aids.
