Recombinant DNA Technology: It is a technique mainly used to change the phenotype of an organism (host) when a genetically altered vector is introduced and integrated into the genome of the organism. So, this is a process which involves the introduction of a foreign piece of DNA structure into the genome which contains our gene of interest.
Stanley Cohen and Herbert Boyer constructed the first artificial recombinant DNA. They inserted antibiotic-resistant genes in the plasmid of Salmonella typhimurium
In this technology gene which is introduced is the recombinant gene.
There are multiple steps, tools and other specific procedure followed in the recombinant DNA technology, which is used for producing artificial DNA to generate the desired product.
