In Its Integrated State the Lambda Chromosome is Known as A

Question

In its integrated state the lambda chromosome is known as a:
A) Lyophilized phage
B) Prophage
C) Metaphage
D) Lytic phage
E) None of these

Accepted Answer

When the lambda phage inserts its DNA into the host bacterium's chromosome, it is called a prophage. The prophage, as part of the host's chromosome, remains dormant until it is triggered to enter the lytic cycle and produce new phage particles. Lyophilized phage is a term used to describe phage particles that have been freeze-dried for preservation. Metaphage and lytic phage are not recognized terms.
