The results of the fundamental research in genetics and genetic engineering are the basis for the further development of biotechnology, whose basics have already been covered in part I of the biotechnology series. In conjunction with findings in microbiology, biotechnology has made significant progress. In particular the identification of the genetic code has opened up new possibilities for numerous applications. It has enabled the genetic modification of organisms for a desired purpose. The close cooperation between different disciplines in biotechnology continuously generates new insights and possible applications. Moreover, in the so-called red biotechnology – which is medical biotechnology – biologists, medical scientists and pharmacists contribute, amongst other things, to the development of new medicines, thus creating a link between scientific fundamental research and its medical application. An important example of red biotechnology is the production of insulin.
