Understand the context: A prophage is related to bacteriophages, which are viruses that infect bacteria.
Recognize that a prophage is a stage in the life cycle of a bacteriophage, specifically during the lysogenic cycle.
In the lysogenic cycle, the viral DNA is integrated into the host bacterium's chromosome, becoming a prophage.
The prophage can remain dormant within the bacterial genome until certain conditions trigger its activation.
Thus, a prophage is best described as a viral genome that has been incorporated into a bacterial cell's chromosome.
