Detailed explanation-1: -Using recombinant DNA technology, scientists are able to create new DNA sequences that would not naturally exist under normal circumstances and environmental conditions. The resulting recombinant DNA is put into a host cell, where it is expressed into a new protein, which is the so-called recombinant protein.

Detailed explanation-2: -The biotechnology industry uses recombinant DNA to isolate, improve, and produce protein therapeutics such as insulin, human growth factor, interferon, erythropoietin (Epogen), and filgrastim (Neupogen). Many other therapeutic recombinant proteins are clinically used or are under development.

Detailed explanation-3: -Recombinant communicator proteins include interferons alfa-2a and alfa-2b and granulocyte-macrophage colony-stimulating factor (immune system modulators); epidermal growth factor and erythropoietin (tissue repair promoters); and human insulin, growth hormone, and atrial peptide (metabolism modulators).

Detailed explanation-4: -Recombinant DNA technology involves transferring genes from one organism to another, or changing genes in an organism by altering their DNA to produce a desired product. Genetic modification involves altering an organisms characteristics (DNA) by the use of genetic engineering.
