A plasmid vector contains a single ecori site in the polylinker (multiple cloning site). an insert is flanked by two ecori sites, one at each end. you cut the vector and the dna containing your insert with ecori and ligate the two. how many ecori site(s) are present in the recombinant dna molecule and how many band(s) would you see when you run your ecori digest of the recombinant dna on a gel? (there is no internal ecori site in the insert dna.)
