What are SOS gene products? How are they induced? A. SOS proteins (RecA, SSB, uvrABC, etc); nicked DNA binds to the Lac repressor, causing its release and degradation, thereby triggering expression of the SOS genes B. SOS proteins are the heat-shock proteins; the “chi” sequence binds to some transcription factors inducing expression of these genes C. SOS proteins are only transcription factors that activate other genes; DNA damage causes induction of these transcription factors through single-stranded DNA binding proteins D....
