A DNA sequence motif is often found near open reading frames and contains consensus sequences for binding sites of transcription factors.Most likely, this sequence is
A) telomeric.
B) centromeric.
C) a regulatory sequence.
D) a tRNA gene.
E) an rRNA gene.

Question

Quizplus · Accepted Answer

The presence of consensus sequences for binding sites of transcription factors suggests that this sequence is involved in the regulation of gene expression. Therefore, the most likely choice is a regulatory sequence. The other options, telomeric, centromeric, tRNA gene, and rRNA gene, do not typically contain binding sites for transcription factors.
