PATHOLOGY

Detailed explanation-1: -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: -Thus, two different fragments of DNA (e.g., a human DNA insert and a DNA vector) prepared by digestion with the same restriction endonuclease can be readily joined to create a recombinant DNA molecule.

Detailed explanation-3: -When a new DNA molecule is derived from two or more sources, the new DNA molecule is known as recombinant DNA. In recombinant DNA, different DNA sequences from different sources or organisms are joined together in a laboratory or experimental set-up that leads to the formation of one new DNA sequence.

Detailed explanation-4: -If two DNA molecules have matching ends, they can be joined by the enzyme DNA ligase. DNA ligase seals the gap between the molecules, forming a single piece of DNA.
