Expert Solution
Lytic and lysogenic life cycle are life cycles of
viruses.Virulent phages like T- even phage shows lytic
cycle.Temperate phages/ Non virulent phages like lambda phage shows
lysogenic cycles.
The phages can reproduce through lysogenic or lytic cycles. In
the lysogenic cycle, the phage DNA inserts into their host genome.
The phage DNA remains inactive inside the bacterial genome and get
replicated when bacterial DNA replicates. Identify the statement as
True or false?
A phage is a virus that infects plants.
The phage that undergoes a lysogenic cycle is called a virulent
phage.
An integrated phage is called a prophage.
A phage that reproduces strictly through the lytic cycle...

How does bacteriophage lambda "decide" whether to enter the
lytic or lysogenic cycle when it infects a bacterium and how does
it execute the decision? Which of the statements below are
correct?
a. In a population of healthy and vigorously growing bacteria
cells it propagates lytically.
b. In a population of poorly growing bacteria cells it
propagates lysogenically.
c. In the lysogenic state, the prophage genome is inactive
(repressed).
d. In the lytic phase, the phage genes for reproduction are...
Which of the following steps is NOT part of the life cycle of a
lytic phage?
A. The phage DNA is transcribed, and the resulting mRNA is
translated to make capsid proteins.
B. The phage DNA integrates into the bacterial chromosome.
C. Phage DNA is injected into the bacterial cell.
D. All of the steps listed are part of the life cycle of a lytic
phage.
E. Many copies of phage DNA are made
