Inside the organism its infected in and in the helper T-cells of the host. 1 of 8 Why does HIV use host cells? It doesn't have the equipment ( like enzymes and ribosomes) to replicate on it's own. 2 of 8 What is the 1st step of HIV replication? The attachment protein attaches to a receptor molecule on the cell membrane of the host helper T-cell. 3 of 8 What is the 2nd step of HIV replication? The capsid is released into the cell, it uncoats and releases genetic material (RNA) into the cell cytoplasm. 4 of 8 What is the 3rd step of HIV replication? Reverse transcriptase is used to make a complementary strand of DNA from the viral RNA template. 5 of 8 What is the 4th step of HIV replication? From the previous step double stranded DNA is made and inserted into human DNA. 6 of 8 What is the 5th step of HIV replication? Host cell enzymes --> make viral proteins. This is from the viral DNA within human DNA. 7 of 8 What is the 6th step of HIV replication? The viral proteins fit into new viruses which bud from the cell and go onto infect other cells. 8 of 8
