WebDNA cloning is the process of making many copies of a specific piece of DNA, such as a gene. The copies are often made in bacteria. In a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid. This step uses restriction enzymes and DNA ligase and is called a ligation. WebFunctional DNA vectors are circular molecules of DNA called plasmids that contain various additional genetic elements that modulate gene expression, termed promoters and enhancers, that are required to achieve expression of …
