NEET 2007 Biology question

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

(1)TATACorrect
(2)TTAA
(3)AATT
(4)CACC

Answer: (1)

Solution

In eukaryotic promoters the RNA polymerase II holoenzyme, with its general transcription factors (TFIID binds first), binds at the TATA box (consensus TATAAA), located about 25-30 bp upstream of the start
