Which of the Following Statements is FALSE Regarding Phage Lambda

Question

Which of the following statements is FALSE regarding phage lambda as a temperate phage?
A) The genome of phage lambda integrates into the genome of the host cell and becomes a prophage.
B) The phage DNA replicates as an integrated prophage but does not produce phage particles.
C) Lambda phage immediately kills its host after infection.
D) The presence of the lambda prophage confers resistant to new infections by lambda.
E) Incorporation of lambda phage DNA into the bacterial genome is called lysogeny.

Accepted Answer

The statement "Lambda phage immediately kills its host after infection" is false. Lambda phage can integrate into the bacterial genome and establish lysogeny, in which the prophage replicates along with the host cell and does not cause lysis. Alternatively, lambda can enter into the lytic cycle and cause host cell lysis to release virions.
