Biology
1 answer:
Veseljchak [2.6K]3 years ago
6 0

Answer:

A

Explanation:

Promoter region on DNA is the point on DNA where polymerase enzyme attaches so it can begin the translation of genes/operon downstream. Terminator region on the DNA is the point that causes the polymerase to terminate transcription. For example, the terminator regions may cause the transcribed nascent mRNA to form a hairpin structure at the terminator sequence hence causing  the polymerase enzyme to detaches from the DNA strand.
