Sommario/riassunto

Biotechnology, an enabling technology, is the growing and most rapidly changing subject which has created a number of new opportunities for the upliftment of human society. It has a broad applications in many diverse aspects of basic research, industry, and commerce. It is a broad field that employs an industrial technology based on the biological synthesis of important chemical compounds, especially proteins (insulin), genetic engineering of plants and animals, and other, related technologies. It also manipulates the genetic information of an organism to allow the characteristics of that orga
