Is it true that the CI repressor functions as both an activator and a repressor of the PRM promoter in lambda phage?
Yes. The CI repressor of lambda phage functions dually, acting as both an activator and a repressor of the PRM promoter to regulate the genetic switch.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The analysis
Both retrieved papers [3] and [9] explicitly state that the CI repressor acts as a dual regulator, serving as both a repressor and an activator of the PRM promoter in lambda phage. There are no papers contradicting this claim, leading to a verdict of SUPPORTED.
