During transcription, RNA polymerase holoenzyme binds to a gene promoter and assumes a saddle-like structure, what is it’s DNA-binding sequence?

1. AATT
2. CACC
3. TATA
4. TTAA

Correct answer: TATA

Solution

The promoter region often contains a TATA box, an AT-rich DNA sequence that helps RNA polymerase holoenzyme bind and correctly initiate transcription. Among the options, TATA is the canonical promoter-binding sequence.
