Question

In prokaryotes, which of the following DNA sequences is typically found in the promoter region?

पर्याय

• Kozak sequence

• TATA box

• Pribnow box

• Palindromic sequence

Answer 1

Prokaryotic promoters characteristically contain the Pribnow box as a key regulatory element. In contrast, eukaryotic promoters contain the TATA box. The Pribnow box is recognized by bacterial RNA polymerase and helps position the enzyme for transcription initiation.
