WebDNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid.The insertion is done using enzymes that “cut and paste” DNA, and it … WebRecognition of different nucleotide sequences determines how DNA will be cut by a restriction enzyme. How does gel electrophoresis separate DNA fragments from each other? Gel electrophoresis separates DNA fragments from each other by applying electric current to a gel so the fragments are separated by change and size.
