Question

Which of the following statements is false?

A) A symbiotic relationship between a phage and a bacterium apparently occurs in the process of lysogeny.
B) Lysogeny is a process that occurs during transformation and conjugation.
C) A bacteriophage that can only undergo lysis is called a virulent phage.
D) A prophage can exist in a quiescent state in the bacterial chromosome.
E) Viral genomes comprise only genes for viral structure and assembly.

Answer 1

The false statement is that in the lysogenic cycle, phage DNA is incorporated into the host genome.

Step-by-step explanation:

The false statement among the given options is C) In the lysogenic cycle, phage DNA is incorporated into the host genome.

In the lysogenic cycle, the phage DNA is indeed incorporated into the host genome, making option C true. The lysogenic cycle is a process where the phage genome integrates into the bacterial chromosome and becomes a part of the host, forming a prophage. This integrated phage DNA can be passed on to subsequent generations of cells during reproduction.

Therefore, the correct option is C) A bacteriophage that can only undergo lysis is called a virulent phage.
