Question
In the lysogenic cycle of bacteriophages, which of the fol-
lowing is true?
(a) Lysogeny is the term applied to a temperate phage that
does not replicate itself independently and does not lyse
the bacterial host cell.
(b) Phage DNA is incorporated into the host bacterium’s
DNA, at which time it is called a prophage.
(c) Temperate phages can be replicated either as a pro-
phage along with bacterial chromosomal replication
or can suddenly revert to the lytic cycle by replicating
themselves and assembling into new phages.
(d) All the above are true.
(e) a and c only.
