Final answer:
The Pribnow box, located about 10 bases upstream from the initiation site for transcription in prokaryotes, has the consensus sequence TATAAT and facilitates the binding of RNA polymerase to initiate transcription.
Step-by-step explanation:
The Pribnow box, also known as the -10 consensus sequence, is located about 10 bases upstream from the initiation site. It has the consensus sequence TATAAT and is responsible for identifying the precise nucleotide at which transcription begins. In prokaryotes, this conserved region is crucial because it is recognized and bound by RNA polymerase, which initiates the process of transcription after binding. This is different from the TATA box in eukaryotes, which also plays a role in transcription initiation by allowing the binding of transcription factors and RNA polymerase.
