Question

Quizplus · Accepted Answer

When viral DNA is integrated into a bacterial chromosome, it is called a prophage. The combination of a bacterial cell and its temperate phage is called a lysogen. Therefore, option A is the correct choice. Option B is incorrect because a plaque refers to a clear area on a bacterial lawn where all the bacteria have been killed by a virus. Option C incorrectly switches the terms prophage and lysogen. Option D is incorrect because a retrovirus is a completely different type of virus that incorporates its RNA into the host's genome.
