Question

Upon injection of a temperate phage genome into a bacterium, which of the following is/are possible outcomes?

a. the phage genome can integrate into the bacterium genome

b. the phage genome is expressed and phage particles are made

c. the bacterium does not lyse

d. phage conversion can happen

e. all stated above are correct

Answer 1

Ans.

a. the phage genome can integrate into the bacterium genome

c. the bacterium does not lyse

Explanation :

Temperate phage is the virus (phage) that shows lysogenic cycle.

In lysogenic cycle, the phage DNA enters into the bacterial cell and integrates into the bacterial DNA (chromosome) to produce the prophage. When the bacterium reproduces, the prophage is also copied and is present in each of the daughter cells of the bacteria.
In lysogenic cycle, the late protein will not synthesized and can not enter to the lytic cycle, its mean the temperate phage (prophage) can not lyse the bacterial cell.
