Question

Recognition sequences of restriction enzymes are generally ___________ nucleotides long. 
 

• A. 2 to 4
• B. 4 to 8
• C. 8 to 10
• D. 14 to 18

Hint:

Common restriction enzymes like EcoRI and HindIII recognize sequences that are usually 6 base pairs long.

Answer 1

The Correct Option is B

Restriction enzymes recognize specific palindromic sequences in DNA, which are typically 4 to 8 nucleotides long. These enzymes are essential in genetic engineering and molecular biology.
