What is the Function of the CII Protein from

Question

What is the function of the cII protein from  λ phage?
A) It represses transcription from PR.
B) It activates transcription from PRM.
C) It activates transcription from PRE.
D) It inhibits cellular proteases that cleave the cI repressor.
E) It antiterminates transcription at tL1.

Accepted Answer

The cII protein from λ phage activates transcription from PRE (promoter for repressor establishment), which is essential for the lysogenic pathway where the phage integrates its DNA into the host genome and remains dormant.
