Once Bound to the Promoter, Core RNA Polymerase ________

Question

Once bound to the promoter, core RNA polymerase ________.
A)breaks the DNA chain in the start site region
B)melts the two DNA strands in the start site region
C)degrades the two DNA strands in the start site region
D)melts the two DNA strands in the termination site region
