HOw does dimerization of transcriptional regulators Increase their specITICity for target DNA sequences O A. Facilitates transport through the nuclear pore complex. O B. Double the number of base pairs the transcriptional regulator interacts with. O C. Allows the dimer to bind more rapidly to the target DNA sequence. OD. Reduces degradation of the dimerized transcriptional requlators.
