The enzyme that is used to cut the specific part of the DNA is called restriction enzyme or RE. Restriction enzymes are called molecular scissors or biological knives. When the DNA molecule is cut with a restriction enzyme, two ends are formed. One blunt end and the other sticky end. About 250 types of restriction enzymes have been obtained from bacteria. Scientist Hamilton Smith (Hamilton Smith) and his colleagues (1970) discovered restriction enzymes.
