life cyle – the steps for an organism to reproduce or replicate.

The HIV life cycle includes:

  • Attachment and binding to a CD4 cell).
  • Fusion or joining the cell.
  • Reverse transcription. When the single strand RNA becomes a double strand DNA.
  • Integration. When the new double-strand virus enter the CD4 cell nucleus and is integrated into humn DNA.
  • Replication. When new viral material is produced from the nucleus.
  • Assembly and maturation. When new viral mateiral is cut up and reassembed to become new active virus.
  • Budding. When the new virus leaves the CD4 cell.
