(T)How does HIV reduce the immune system of an infected person? Explain the steps of how HIV gets into the immune system
1. The envelope glycoproteins enable the virus to bind to specific receptors on certain whtie blood cells
2. The virus fuses with the cell's plasma membrane. The capsid proteins are removed(becomes capsomeres), releasing the viral proteins and RNA.
3. Reverse transcriptase catalyzes the synthesis of a DNA strang complementary to teh viral RNA.
4. Reverse transcriptase catalyzes the syntheis of a second DNA strand complementary to the first
5. The double-stranded DNA is incorporated as a provirus into the cell's DNA.
6. Proviral genes are transcribed into RNA molecules, which serve as a genomes for the next viral generation and as mRNAs for translation into viral protein.
7. The viral proteins include capsid proteins and reverse transcriptase (made in the cytosol) and envelope glycoproteins (made in the ER)
8. Vesicles transport the glycoproteins to the cell's plasma membrane.
9. Capsids are assumbled around viral genomes and reverse transcriptase molecules.
10. New viruses bud off from the host cell
