Transcription factors are
A) RNA sequences that bind to RNA polymerase.
B) DNA sequences that regulate transcription.
C) proteins that bind to the DNA promoter sequence.
D) polysaccharides that bind to the transcripts.
E) factors that bind to enhancers.

Question

Quizplus · Accepted Answer

Transcription factors are proteins that bind to specific DNA sequences, usually in the promoter region, to regulate transcription. They can activate or repress gene expression by recruiting or inhibiting RNA polymerases and other components of the transcription machinery. Some transcription factors can also bind to enhancer sequences located far from the promoter and enhance transcription indirectly. RNA sequences (A) do not generally bind to RNA polymerase, and polysaccharides (D) do not interact with DNA or RNA.
