D. AATATT
Answer: Option B
Solution(By Examveda Team)
TATAAT is the sequence of Pribnow Box.The Pribnow box is a sequence of TATAAT of six nucleotides that is an essential part of a promoter site on DNA for transcription to occur in bacteria.
It is an idealized or consensus sequence that is, it shows the most frequently occurring base at each position in many promoters analyzed, individual promoters often vary from the consensus at one or more positions.
It is also commonly called the -10 sequence because it is centered roughly ten base pairs upstream from the site of initiation of transcription.
