Question 4

DNA viruses cause disease when the host cell uses the viral DNA to produce more viruses. The host cell uses the viral DNA to make viral proteins as well as more viral DNA; these are then used to produce more viruses and cause disease. In a eukaryotic cell, the viral DNA is often inserted into the host genome. Explain why viral DNA that stays in the cytoplasm would not cause disease.

In a eukaryotic cell, the enzy...

Question 5

Bacteria and humans use the same DNA components, and both kinds of cells also perform transcription and translation. Which of the following choices is a potentially significant outcome of this shared mechanism?
