This publication titled “Encyclopaedia of Biotechnology & Genetic Engineering” is an initiative to deal with the subject in its totality. Biotech refers to the biological science, applied especially in genetic engineering and recombinant InTechnology. Biotechnology deals with a setoff biological techniques developed through basic research and now applied to research and product development. It is the means or way of manipulating life forms (organisms)to provide desirable products for man’s use. For example, beekeeping and coffle breeding could be considered to be biotechnology related endeavors. However, usage of the word biotechnology in the United States has come to mean all parts of an industry that knowingly create, develop, and market variety of products through the willful manipulation, on a molecular level, of life forms or utilization of knowledge pertaining to living systems.
