HIV is a retrovirus with two single strands of RNA
genome.
- A virus infects white blood cells
by binding to receptor proteins in the plasma membrane
of the host.
- Its
RNA
and enzymes
enter the host by endocytosis.
- The viral enzyme reverse transcriptase
copies the RNA
genome into DNA.
- The viral DNA
is then inserted into the host DNA using the viral enzyme integrase.
