Gene cloning is the process in which a gene of interest is located and copied (cloned) out of DNA extracted from an organism. When DNA is extracted from an organism, all of its genes are extracted at one time. This DNA, which contains thousands of different genes.
Gene cloning is making of multiple copies of a single gene, by which we can make a pure copy of individual gene. These cloning have been used in many sectors of biomedical and industrial research. Alteration of the gene sequence for the production or change of protein product or cloning of genes into new organism is the main domain process of genetic engineering.
