Some restriction enzymes produce DNA fragments with overhanging stretches called sticky ends on each strand. Sticky ends are useful in making recombinant DNA because
Select one:
a. Sticky ends contain the exact same nucleotides that allows fragments to splice together.
b. Sticky ends contain nucleotides with complementary bases that allows fragments to splice together.
c. Sticky ends contain the exact same nucleotides that can form hydrogen bonds.
d. Sticky ends contain nucleotides with complementary bases that can form hydrogen bonds.
The function of a restriction enzyme is to
a. prevent the movement of DNA outside the nucleus
b. separate the DNA double helix
