Following HIV infection of a T cell, the virus replicates by creating a DNA copy of its RNA, integrating it into the host DNA, utilizing host cell mechanisms to synthesize viral components, and assembling new viruses that bud off.
After infecting a T cell, HIV replicates by making a DNA copy of its RNA, integrating this DNA into the host cell's DNA, using the host cell's machinery to produce viral proteins and RNA, assembling new viruses, and releasing them via budding.
| Front | Describe how new viruses are produced after HIV has infected a T cell (3 marks) |
|---|---|
| Back | DNA copy made (of viral RNA); Inserted into host DNA / chromosomes; (Uses viral DNA to) make viral proteins/particles; Makes viral RNA; (Host) cell makes new viruses; "Budding off" / wrapped in cell membrane; Accept reverse transcriptase makes DNA for 2 marks in correct context; |
