A researcher discovered Suramin as a potent and selective inhibitor of Mycobacterium tuberculosis RecA protein and the SOS response. What would be the outcome if the action of RecA was inhibited during the SOS response? O LexA would not autolyse, and therefore the transcription of DNA repair genes would not occur; the bacteria would likely not survive. O LexA would autolyse, and therefore the transcription of repair genes would not occur; that would be lethal to the bacteria. LexA would autolyse, and therefore the transcription of DNA repair genes would occur; and the bacteria will be susceptible to antibiotics. LexA would not autolyse, and therefore the transcription of repair genes would occur; essentially that would be lethal to the bacteria.
