Answer:
1. Restriction enzymes are endonucleases, that is, enzymes that digest nucleic acids. Restriction enzymes recognize specific sequences of nucleotides in a DNA strand. Their use allows the detection of point mutations in DNA and eliminates the need for subcloning and sequencing.
Traditionally, four types of restriction enzymes are recognized, designated I, II, III, and IV, which differ primarily in structure, cleavage site, specificity, and cofactors.
b. answer is attached.
c. Multiplying the genome size by the frequency equals the number of restriction fragments produced, or (2.5 x 107 bp)(2.56 x 10-4 bp-1) = 6400 fragments. Divide the genome size by the number of fragments to determine the average fragment size, or 2.5 x 107 bp/6400 = 3.9 x 103 bp.]
