Which DNA Sequence Would Most Likely Be Recognized by a Restriction

Question

Which DNA sequence would most likely be recognized by a restriction enzyme?
A) AGTCGA
B) GTCTGA
C) TAAGGT
D) TAGCTA
E) TCGTGGA

Accepted Answer

Restriction enzymes typically recognize and cleave DNA sequences that are palindromic, meaning they read the same forward and backward on complementary strands. Option D, TAGCTA, is palindromic when its complementary strand is read in reverse, making it the most likely to be recognized by a restriction enzyme.
