Which of the following a feature of TATA boxes?
A)They are found outside the core sequence of a gene regulatory sequence.
B)They are found downstream of the gene being transcribed.
C)They reside in the enhancer regions.
D)They represent an area of DNA more easily opened than other areas.

Question

Quizplus · Accepted Answer

TATA boxes are AT-rich sequences found approximately 25-30 base pairs upstream of the transcription start site of many eukaryotic genes. They represent an area of DNA that is more easily opened than other areas, potentially allowing for easier access by RNA polymerase and other transcription factors.
