The TATA box is similar to the _______ in E. coli.
A) -35 promoter sequence
B) -10 promoter sequence
C) +1 transcription start site
D) None of the above

Question

Quizplus · Accepted Answer

The TATA box in eukaryotic promoters is similar to the -10 promoter sequence in E. coli, as both regions are recognized by RNA polymerase and are involved in the initiation of transcription. The -35 promoter sequence in E. coli is also recognized by RNA polymerase, but it serves a slightly different function than the TATA box in eukaryotic promoters. The +1 transcription start site is not similar to the TATA box in any way. Therefore, the best choice is B, the -10 promoter sequence.
