Acertain 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'
