9. Transcription HIV and AIDS Copying DNA into RNA Reverse Transcription? Copying RNA into DNA

10. HIV: A retrovirus Receptors: CD4 molecules Coreceptors: fusin, CCR5 HIV and AIDS

11. Retroviruses (RNA Virus) Retroviruses have an enzyme (called reverse transcriptase) that is capable of reverse transcribing their RNA into DNA . This viral DNA can then be integrated into the host cell’s genome. HIV and AIDS

16. Retroviruses (RNA Virus) Retroviruses replicate with a high mutation rate, because reverse transcriptase makes several errors! This increases it’s ability to evolve and survive. HIV and AIDS Some mutations will change the virus’ “appearance” and make it unrecognizable to the immune system

20. HIV targets helper T-Cells HIV and AIDS

21. HIV and AIDS Helper T-cells are essential to the immune system HIV infects helper T-cells Therefore HIV stops the immune system from working

22. Helper T-cells are essential to the immune system HIV and AIDS HIV Destroy foreign cells Kill infected cells
