WebCloning may involve cloning small DNA fragments (molecular cloning), or cloning entire organisms (reproductive cloning). In molecular cloning with bacteria, a desired DNA fragment is inserted into a bacterial plasmid using restriction enzymes and the plasmid is taken up by a bacterium, which will then express the foreign DNA.

WebOct 13, 2024 · Type II restriction enzymes are commonly used in restriction cloning workflows. These enzymes cleave DNA sequences into fragments at or near specific recognition sites. The cleavage can produce “sticky” or “blunt” ends of DNA that can be ligated to other DNA fragments that possess compatible ends. WebThe ability of some restriction enzymes to predictably cleave DNA and generate distinct DNA bands with ligatable ends has made them an invaluable tool for recombinant DNA …
