Which statement best explains the results under low glucose, no lactose, conditions when db-camp is present? the cap protein comes off its site on the dna, but the repressor protein remains bound, and rna polymerase cannot bind to the lac operator. the repressor protein binds db-camp and comes off its site on the dna, but the cap protein remains bound, thereby preventing rna polymerase from binding to the lac operator. the cap protein and repressor come off their sites on the dna, but db-camp prevents rna polymerase from binding to the lac operator. the cap protein binds db-camp and binds to its site on the dna, but the repressor protein remains, thereby preventing rna polymerase from binding to the lac operator.
