You have identified a mutation in a gene that seems to decrease transcription of another gene 2000 bp away from the mutation site. what regulatory sequence, which may be found within another gene, has likely been mutated in this instance?

Enhancer sequence

Explanation:

Hi! The answer you're looking for would be enhancer sequence. This is the answer because enhancer sequences are regulatory DNA sequences that, when bound by specific proteins called transcription factors, enhance the transcription of an associated gene. In this case, that would be the mutation in a gene that seems to decrease transcription of another gene 2000 bp away.
