WebBy selecting the appropriate enzyme (s), one can either linearize a plasmid to determine the size of the entire construct or excise some or all of an insert from it. Before beginning your diagnostic digest, you will need to select … WebEach type of enzyme typically only reacts with one, or a couple, of substrates. Some enzymes are more specific than others and will only accept one particular substrate. Other enzymes can act on a range of molecules, as long as they contain the type of bond or chemical group that the enzyme targets.
