Question

A "sticky end" is the result of this process. a. Restriction enzymes reconnecting DNA b. Restriction enzymes cutting DNA c. DNA ligase reconnecting DNA d. Restriction enzymes destroying DNA

Answer 1

Answer:

b. Restriction enzymes cutting DNA

Explanation:

Restriction enzymes are the enzymes that cut the DNA molecules. Their specific feature is that they digest the specific DNA sequences only. These specific DNA sequences are called restriction sites. When some restriction enzymes digest the DNA, DNA fragments with single-stranded ends are produced. These single-stranded overhangs are called sticky ends. They are called so since the DNA fragments produced by digesting DNA with one restriction enzyme have complementary overhangs that spontaneously base pair.
