Final answer:
The hepatitis C virus replicates in high numbers and has a high mutation rate. Challenges to the treatment of Hepatitis C infection include lack of awareness and expensive antiviral drugs. HIV proteins available inside the host cell include reverse transcriptase, integrase, Vpu, Vif, and Nef. AIDS develops when the CD4+ T cell count drops below a certain level. Immediately after HIV uncoats inside human cells, reverse transcription occurs. The only way out of the human cell for HIV starts with translation.
Step-by-step explanation:
1. The correct answer is b. The hepatitis C virus replicates in high numbers and has a high mutation rate. This high mutation rate allows the virus to quickly adapt to changes in its environment, including developing resistance to antiviral drugs.
2. The challenges to the treatment of Hepatitis C infection include b. Individuals unaware of their infection and extremely expensive antiviral drugs. Many people with Hepatitis C are undiagnosed, which delays treatment, and the cost of antiviral drugs can be a barrier to access.
3. The correct answer is c. None in this list. The proteins available inside the host cell for HIV are reverse transcriptase, integrase, Vpu, Vif, and Nef.
4. The correct answer is b. AIDS develops when the CD4+ T cell count drops below a certain level. CD4+ T cells are essential for the immune response, and when their numbers decrease, the immune system becomes compromised.
5. The correct answer is b. Reverse transcription occurs immediately after HIV uncoats inside human cells. Reverse transcription is the process in which the viral RNA is converted into DNA.
6. The only way out of the human cell for HIV starts with this step: c. translation. Once the HIV DNA has integrated into the host cell's genome, it can be transcribed and translated to produce new viral proteins and genomes.
