Question

Quizplus · Accepted Answer

Restriction enzymes recognize DNA sequences that are palindromes, meaning they read the same backward and forwards. This is important for the enzyme to cut both strands in a specific location. A-T rich or C-G rich sequences may be present in the palindrome, but they are not what the enzyme directly recognizes. Complementarity and stickiness are properties of how the cut ends of DNA are left after the enzyme cuts the DNA.
