Question

In an experiment, a scientist makes a radioactively labeled probe using viral DNA. She then discovers that the probe hybridizes to a small segment of DNA isolated from human tissue. What can she conclude from her results?

Answer 1

Out of the following given choices;

A. The Geiger counter being used to detect radiation is broken.

B. Two or more samples we accidentally swapped, causing confusion.

C. A virus contaminated the reaction in which the probe was made.

D. The human genome might contain at least one viral gene.

 

The answer is D. This means that the viral DNA inserted itself in the human tissue DNA aand became a prophage. A prophage is a latent form of viral infection where the inserted viral DNA has no interference with the host cell biochemical processes. The prophage will be present in the daughter cells of the host cells.

Answer 2
