Question

IF a repressor (R1) binds to the promoter of another repressor (R2) to outcome is (R1>R2=?)? A. two repressors (R1+R2) in a row result in super repression. (R1>R2=2XR) B. nothing happens because the first repressor doe snot interfere with the second repressor (R1>R1=R) C. activation of transcription because a repressor prevents the activation of another repressor which results in activation of transcription (R1>R2=A) D. nothing happens because both regulators (repressor) are redundant (R1>R2=0)

Explanation / Answer

C. Activation of transcription because a repressor prevents the activation of another repressor which results in activation of trabscription.

Whatever R2 repressor will now be expressed.
