Restriction Enzymes: A History

WebThe restriction enzyme is a protein produced by bacteria that cleaves the DNA at specific sites. This site is known as the restriction site. The restriction enzymes protect the live bacteria from bacteriophages. They recognize and cleave at the restriction sites of the bacteriophage and destroy its DNA. Restriction enzymes are important tools ... WebThe termini produced by EcoR I, since they are complementary at their single-stranded overhangs, are said to be cohesive or “sticky.”. A number of restriction enzymes have been isolated from a variety of microbial sources. Recognition sites for specific enzymes range in size from 4 to 13 base pairs, and, for most restriction enzymes used in gene cloning, are … WebHistory and Applications of Restriction Cloning.
