Protein X recognizes and binds to a particular (normal and undamaged) DNA sequence. Which statement applies?
A. The protein must have a cofactor to separate the DNA strands to access and recognize the sequence.
B. The protein can recognize sequence-dependent differences in the distance between the sugar-phosphate backbones of the two strands.
C. The protein can recognize the sequence by accessing the bases at the major or minor groove.
D. The protein must be dimeric to recognize the complementary sequences on each strand.
