Question

A certain restriction enzyme cleaves double-stranded DNA at the sequence shown below, where the slash indicates where each strand is cleaved. Note that the cleavage results in a two-base pair single-stranded region at the 5' end that allows the cleaved ends to undergo base pairing.
5'-AA/ATTT-3'
3'-TTTA/AA-5'
Which of the restriction enzymes, that cleave double-stranded DNA as shown below, would produce overhanging ends able to pair with those produced by the enzyme described above?

A. 5'-GGAT/CC-3'
3'-CCTA/GG-5'
B. 5'-GGA/TCC-3'
3'-CCT/AGG-5'
C.5'-AATA/TT-3'
3'-TT/ATAA-5'
D. 5'-GG/ATCC-3'
3'-CCTA/GG-5'
E. 5'-AAA/TTT-3'
3'-TTT/AAA-5'
