Answer 1

A promoter is a DNA sequence where the transcription machinery binds and initiates transcription.

Step-by-step explanation:

Promoter is the answer to your question. A promoter is a DNA sequence where the transcription machinery binds and initiates transcription.

It is usually found upstream of the gene it regulates. The specific sequence of a promoter is important as it determines how frequently the corresponding gene is transcribed. Promoters in prokaryotes have consensus sequences at -10 and -35 positions, while eukaryotic promoters are larger and more complex.
