Genetic Engineering and r DNA Technology

Genetic engineering is the manipulation of an organism's genome using biotechnology Principles. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species domains for the production of improved or novel organisms. Genetic engineering has applications in medicine, research, industry and agriculture and can be used on a wide range of plants, animals and microorganisms. Tissue engineering is the use of a integration of cells, engineering and materials principles, and suitable biochemical and physicochemical factors to improve or replace biological tissues.
