Question

1. what role does the enzyme dna polymerase play in transcription, related to the promoter and terminator sequences on dna? it knows where to begin transcribing and where to stop. it knows when a strand of mrna should leave the cells nucleus. it knows which codons are needed to replace thymine with uracil. it knows how to synthesize dna from mismatched codons.

Explanation:

In transcription, DNA polymerase binds to the promoter sequence on DNA to start the process and stops when it reaches the terminator sequence. It has no role in mRNA leaving the nucleus, codon - uracil replacement, or DNA synthesis from mismatched codons.

Answer:

It knows where to begin transcribing and where to stop.
