Protein Production by BiotechnologyThere are very few parts of biology that remain free from the influence of Genetic Engineering developed in the early 1970s. Disciplines as wide apart as Brewing, Forensic Science and Population Genetics have all been affected in some way. The major impact, however, has been to create a new science of Biotechnology a part of which is the production of proteins in a variety of cellular systems. Initially, bacterial systems such as E. coli were used but
