Understand the concept of a promoter sequence: Promoter sequences are regions of DNA that initiate transcription of a particular gene. In prokaryotes, these sequences are crucial for the binding of RNA polymerase and the initiation of transcription.
Identify common prokaryotic promoter sequences: In prokaryotes, typical promoter sequences include the Pribnow Box (also known as the -10 sequence) and the -35 consensus sequence. These sequences are recognized by the sigma factor of RNA polymerase.
Recognize the TATA Box: The TATA Box is a promoter sequence commonly found in eukaryotes, not prokaryotes. It is located approximately 25-30 base pairs upstream of the transcription start site in eukaryotic genes.
Evaluate the given options: Compare each option to the known prokaryotic promoter sequences. The Pribnow Box and the 35bp consensus sequence are typical prokaryotic promoter sequences.
Determine which option is not a prokaryotic promoter sequence: Based on the information, identify the TATA Box as the sequence that is not an example of a prokaryotic promoter sequence.

Open Question
A mutant strain of Salmonella bacteria carries a mutation of the rho protein that has full activity at 37°C but is completely inactivated when the mutant strain is grown at 40°C.Speculate about the kind of differences you would expect to see if you compared a broad spectrum of mRNAs from the mutant strain grown at 37°C and the same spectrum of mRNAs from the strain when grown at 40°C.
