Question

Quizplus · Accepted Answer

Establishment of lysogeny in E. coli cells requires a high concentration of cI protein, which binds to the P_RE regulatory site. Cro protein is actually involved in preventing lysogeny and favors lytic cycle in bacteriophages. CII and CIII are not directly involved in the establishment of lysogeny. Therefore, the correct option is D with cI and cII.
