A DNA sequence is cut by two different restriction enzymes (1 and 2).
Digestion from enzyme 1 yields the following fragments (read in the 5ʹ-to-3ʹ direction): CGATAC, GTCGTCGCC, and GTTATCGCGAC.Digestion from enzyme 2 yields the following fragments (read in the 5ʹ-to-3ʹ direction): CGACGTCGTCGCC and CGATACGTTATCG.
Which sequence does enzyme 1 recognize as a site at which to cut?
(Note that the enzyme cuts in the middle of its recognition sequence.)
A) GTTA
B) ACGT
C) TGGA
D) CGCG
E) GTCG
