Questions and Answers

What is the role of HCV RNA in the host cell?

It is cleaved by proteases to produce a polyprotein

It serves as a template for DNA replication

It is a receptor for attaching to the host cell

It serves as a template for viral RNA replication and as messenger RNA for protein production (correct)

What is the result of the protein produced by HCV RNA?

The synthesis of a polyprotein that is cleaved by proteases (correct)

The degradation of the host cell's RNA

The inhibition of the host cell's immune response

The production of new viral particles

How do RNA viruses enter host cells?

By fusing with the host cell membrane

By producing a polyprotein that interacts with the host cell

By attaching to specific receptors and entering the host cell (correct)

By injecting their genetic material into the host cell

Study Notes

HCV Life Cycle

HCV attaches to a specific receptor and enters the host cell.
HCV RNA serves as a template for two purposes:
- Viral RNA replication
- Messenger RNA for protein production (translation)
The protein produced is a polyprotein that undergoes cleavage by proteases.
Two potential drug targets for treating HCV:
- HCV RNA polymerase
- HCV RNA protease
