1) Which feature of the life cycle of some viruses may result in the development of cancer?
A. Viral RNA can integrate into the chromosomes of host cells.

2) Think about mitosis in general. What occurs in Prophase, Anaphase, Metaphase and Telophase? What are the end products? Apply this to a HIV infected cell.

1) Think about what cancer actually is. It is the rapid and uncontrollable proliferation of cells. Therefore, what causes this?

So, is the answer D for question 1 and B for question 2??

In mitosis the viral DNA will be replicated so that when the parent cell divides the daughter cells will contain the equal volume of genetic material.

I'd say so! Mutagens can increase the rate of the cell cycle, thus cellular equilibrium cannot be maintained and so more cells are produced in comparison to the number of cells dying.

I thought HIV is a RNA virus, so its RNA would be replicated

Although please correct me if I'm wrong
