The restriction enzyme HaeIII recognizes and cuts the DNA sequence
5'-GGCC-3'
3'-CCGG-5'
a. How many DNA fragments would be expected to be produced upon digestion of the plasmid pUC18DNA with HaeIII (plasmid pUC 18 contains 2686 base-pairs of DNA).
b. Would a larger or smaller number of DNA fragments to be produced by digestion of phage lambda DNA with HaeIII.
