RNA polymerase:
A) binds tightly to a region of DNA thousands of base pairs away from the DNA to be transcribed.
B) can synthesize RNA chains without a primer.
C) has a subunit called $\lambda$
(lambda), which acts as a proofreading ribonuclease.
D) separates DNA strands throughout a long region of DNA (up to thousands of base pairs), then copies one of them.
E) synthesizes RNA chains in the 3' $\rightarrow$ 5' direction.
