Practice questions

1 of 50Practice questions for this set
In a bacteriophage study, E. coli cultures infected at low multiplicity of infection showed no immediate drop in optical density, but PCR of host DNA detected a stable viral genome segment at a specific chromosomal locus for >20 generations. When the culture was exposed to UV light, extracellular phage particles increased sharply and cell density declined. Which conclusion is most consistent with the viral life cycle?
