a batch of this DNA is first fully digested by Hpal alone, then another batch is fully digested by HindIII alone, and , finally a third batch is fully digested by both Hpal and HindIII together. The fragments resulting from each of the three digestions are place in separate wells of an agarose gel, separated by electrophoresis, and stained by ethidium bromide. draw the bands as they would appear on the gel (indicate the sizes in kb of each band/DNA fragment).
