Biotechnology is the use of living systems and organisms to develop or make useful products. In Colleges for Biotechnology, intense studies related to technological application is included which uses biological systems, living organisms or derivatives. To make or modify products or processes for specific use, Colleges for Biotechnology are encompassing curriculum emphasizing biotechnology in agriculture, food production and medicine. Colleges for Biotechnology has revised studies related to new and diverse sciences such as genomics, recombinant gene technologies, etc. Biotechnology is utilizing the sciences of biology, chemistry, physics, engineering and information technology to develop tools and products to apply to living cells/organisms. Genetic Engineering Genetic engineering is the study of knowledge obtained from genetics to alter the reproduction and hereditary processes of organisms. It deals in cloning, in-vitro fertilization, species hybridization or direct manipulation of the genetic material itself by the recombinant DNA technique. Plant Tissue Culture Functions in the field of in-vitro regeneration and propagation of plantlets, a Tissue Culture specialist may also be involved in plant germ plasma conservation. Plant Genetics Activities to improve plants by evolving new horticultural varieties through hybridization, this work is generally carried out in the laboratories.
