A) RNA polymerases usually do not need a template, while DNA polymerases do.
B) DNA polymerases usually require a primer (i.e., they can only continue a strand, not start one), while most RNA polymerases do not.
C) RNA polymerases usually synthesize introns, while DNA polymerases synthesize cistrons.
D) RNA polymerases polymerize 5' → 3', while DNA polymerases polymerize 3' → 5'.
E) None of these

A) the start site for transcription in DNA
B) the binding site for regulatory proteins that stimulate transcription
C) the general region of DNA downstream from the start site
D) the site on DNA at which RNA polymerase binds to initiate transcription
E) None of these

A) The release of pyrophosphate from a nucleoside triphosphate drives the reaction.
B) RNA is synthesized from the 5' end to the 3' end.
C) DNA to RNA base pairing includes A to U and G to C.
D) Transcription requires the use of a primer.
E) None of these
