Q34.
It is very important to study lambda biology as lambda phages are used for cloning purposes. Which of the statement is true for lambda phage?

a.

It is an example of temperate phage

b.

The fate of the phage is decided before it infects the cell

c.

The lysis fate is that where the phage inserts its genome into the bacterial genome and the replication goes on
