Which of the following sequences is likely to be recognised by a class II restriction endonuclease? Many prokaryotic promoters contain the core sequence 5'-TATAA-3'. Which of the sequences below might be capable of acting as a promoter?
Understand the Problem
The question is asking which of the given DNA sequences is recognized by a class II restriction endonuclease and which sequences can act as a promoter, specifically related to prokaryotic biology. It involves identifying DNA sequences based on their biological function.
Answer
5'-AGGCCT for endonuclease, 5'-ACCCTTTATACTGTAA for promoter.
The sequence likely recognized by a class II restriction endonuclease is 5'-AGGCCT. The sequence that might act as a promoter is 5'-ACCCTTTATACTGTAA.
Answer for screen readers
The sequence likely recognized by a class II restriction endonuclease is 5'-AGGCCT. The sequence that might act as a promoter is 5'-ACCCTTTATACTGTAA.
More Information
Class II restriction endonucleases often recognize palindromic sequences like 5'-AGGCCT. The TATA box core is present in the second sequence 5'-ACCCTTTATACTGTAA, indicating potential promoter activity.
Tips
Look for palindromic sequences for class II restriction sites and TATA-like sequences in promoters.
