Once RecA is no longer activated,what happens to the SOS regulon?

Question

Quizplus · Accepted Answer

Once RecA is no longer activated, LexA builds up and represses the SOS regulon. This is because LexA is a repressor protein that inhibits transcription of the genes in the SOS regulon. When DNA damage occurs, RecA is activated and binds to LexA, leading to its autocleavage and subsequent inactivation. This allows the genes in the SOS regulon to be transcribed and repair the DNA damage. However, once the damage is repaired and RecA is no longer active, LexA can build up and repress the SOS regulon again to maintain normal cellular function.
