In the Lysogenic Bacteriophage Life Cycle,the λ Chromosome

Question

In the lysogenic bacteriophage life cycle,the λ chromosome
A)replicates and the phage genes take over the bacterium.
B)inserts itself physically into the host cell's chromosome.
C)expresses a repressor protein gene that inhibits the lytic pathway.
D)is replaced by a piece of bacterial DNA when packaged inside phage progeny.
E)Both B and C

Accepted Answer

In the lysogenic cycle of bacteriophage λ (lambda), the phage DNA integrates into the bacterial chromosome (B) and expresses a repressor protein that inhibits the transition to the lytic cycle, thereby maintaining the lysogenic state (C).
