Question
The TATA box is a part of the _________ region.
Answer: Option B
:
B
The first step of transcription is called initiation, during which the enzyme RNA polymerase binds on to the promoter region. Many eukaryotic genes have a conserved promoter sequence to begin with, called the TATA box, located 25 to 35 base pairs upstream of the transcription unit. This region always has the sequence TATAAA on one DNA strand, and ATATTT on the complementary strand. RNA polymerase specifically identifies this region on the DNA molecule to initiate transcription.
