Biotechnology is a turf of practical biology that involves the use of living organisms and bioprocesses in engineering, technology, medicine and other fields require bioproducts. Biotechnology also utilizes these products for developed purpose. Contemporary use of alike terms includes hereditary engineering as well as cell- and tissue civilization technologies. The concept encompass a wide variety of procedures (and history) for modify living organisms according to human purposes leaving back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. By contrast to biotechnology, bioengineering is usually consideration of as a related field with its emphasis more on higher systems approach (not necessarily altering or using biological resources directly) for interfacing with and utilizing living things..
