Right, I have read about the promoter, but I am hung up on the part where
there is only one codon for the start code. So how is it that the
polymerase gets the correct strand given that the same codon is in multiple
locations? Does it already "know" what the base sequence is going to look
like and there fore skips over obviously incorrect base sequences, or are
the codons different on DNA than they are on RNA, resulting in more variety
of start and stop codons than just start= AUG, Stop = UAA,UAG,UGA as in RNA?
