Steps of HIV Replication
1. Binding and Fusion- HIV binds with CD4 and CCR5 receptors. Once inside, it releases its genetic material into the cell.
2. Reverse Transcription- The enzyme, reverse transcription, changes the genetic material of the virus
3. Integration- The virus' new genetic material enters the nucleus of the CD4 cell and uses an enzyme called integrase to integrate itself into the cell's DNA.
4. Transcription- The virus uses the cell to create more of its own genetic material
5. Assembly- An enzyme cuts the longer HIV proteins into individual proteins
6. Budding- The virus pushes itself out of the cell, taking part of the membrane with it (so it can begin the process again.)
