Hide < Question 4 of 10 > © Macmillan Learning What occurs as a result of allolactose binding to a repressor protein? O The repressor falls off the DNA, allowing RNA polymerase to begin transcription. O The repressor falls off the DNA and inhibits binding of RNA polymerase. O The repressor is released from the DNA and binds to specific proteins for degradation. O The repressor changes shape and binds to the activator.
