1.Define Recombinant DNA technology?
The technology which involves the joining of DNA molecules and producing artificial DNA by inserting them into a suitable host from two different sources is known as Recombinant DNA technology.  It is also popularly named as Genetic engineering. Swiss microbiologist Werner Aber discovered restriction enzymes in 1968 which leads to the emergence of recombinant DNA technology. Insertion of a foreign piece of DNA which contains the gene of interest into the genome. This gene which is introduced is called recombinant gene and its process is called Recombinant DNA technology. The recombinant DNA is then maintained within the host.
