Solution
The correct option is D GTCGAC
- Restriction enzymes are found in bacteria (and other prokaryotes). They recognize and bind to specific sequences of DNA, called restriction sites. Each restriction enzyme recognizes just one or a few restriction sites.
- A palindromic sequence is a nucleic acid sequence in a double-stranded DNA or RNA molecule wherein reading in a certain direction on one strand matches the sequence reading in the same direction on the complementary strand.
- most restriction enzymes recognize a "perfect" palindrome, Hence GTCGAC(the complimentary sequence is CAGCTG) sequence is most likely to be a restriction enzyme recognization site,
- So, the correct answer is "GTCGAC'.
