Detailed explanation-1: -What is recombinant DNA technology? Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.
Detailed explanation-2: -Recombinant DNA is the method of joining two or more DNA molecules to create a hybrid. The technology is made possible by two types of enzymes, restriction endonucleases and ligase.
Detailed explanation-3: -Recombinant DNA is the general name for a piece of DNA that has been created by combining two or more fragments from different sources. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure, differing only in the nucleotide sequence.
Detailed explanation-4: -This universality-the capacity to mix and match DNA from different species, because DNA has the same structure and function in all species and because restriction and ligase enzymes cut and paste the same ways in different genomes-makes recombinant DNA biology possible.
