The TATA box of the eukaryotic promoter is analogous to which structure of the prokaryotic promoter?
A)sigma
B)the -10 box
C)the -35 box
D)the site of initiation

Question

Quizplus · Accepted Answer

The TATA box of the eukaryotic promoter and the -10 box of the prokaryotic promoter are similar in that they serve as recognition sites for RNA polymerase to bind and initiate transcription. The -35 box of the prokaryotic promoter is also recognized by RNA polymerase but serves a different function than the TATA box. The site of initiation is not a structure within the promoter, but rather the point at which transcription actually begins. Sigma is a subunit of prokaryotic RNA polymerase that helps to recognize the promoter region and facilitate transcription initiation, but it is not directly analogous to the TATA box.
