B)Pribnow boxes
C)TATA boxes
D)promoters

Question

Quizplus · Accepted Answer

Promoters are nucleotide sequences that identify the location of transcription start sites and regulate the level of transcription. Sigma factors are proteins that bind to promoters to initiate transcription, Pribnow box is a specific sequence within bacterial promoters, and TATA box is a specific sequence within eukaryotic promoters. However, promoters are not restricted to a particular group of organisms and are generally defined as the regions of DNA that interact with transcription factors to initiate transcription.
