Which of the following is not a mechanism employed by repressor proteins to decrease transcription of a specific gene?
A) The repressor associates with a promoter element,blocking RNA polymerase from binding promoter element.
B) The repressor binds to the activation domain of an activator,eliminating its ability to increase transcription.
C) The repressor binds to DNA-binding domain of an activator,eliminating its ability to associate with enhancer.
D) The repressor binds to a DNA sequence in an enhancer,eliminating access to sequence by activator.
E) The repressor binds to RNA polymerase II,blocking its ability to associate with promoter element.

Repressor proteins do not typically bind to RNA polymerase II to block its ability to associate with a promoter element. Rather, they typically bind to specific DNA sequences or regulatory proteins to interfere with transcription initiation or elongation.
