what enzyme is necessary to permanently link the digested foreign and plasmid dna together to form the recombinant dna molecule? how does this enzyme work?
what type of ends do the enzymes bamhi and ecori produce? how does this type of end facilitate cloning?
what is the texture and consistency of the dna?
