Some proteins remain in the cytoplasm for cell maintenance and operations. Others are needed in the nucleus some proteins such as digestive enzymes leave the cells for other functions. Summary The following analogy is somewhat exaggerated but The genetic information carried on DNA is analogous to the designer at the top of figure in Chapter 4. The mRNA and transcription are analogous to the process planning steps that convert design information to the specific details of manufacturing. Ribosomes are the sites where proteins are translated or synthesized and thus analogous to fabrication machinery. The proteins are the manufactured product which then do the work of the cells. These proteins can be seen as the workers who bring energy back into the overall system. The created proteins and enzymes subsequently enable other processes such as triggering the promoters which then make copies of the genes. The whole process summarized here thus becomes self-replicating. With the review of both biosciences in Section and bioprocesses in Section some aspects of biotechnology and specifically genetic engineering and manufacturing can now be considered in more detail. GENETIC ENGINEERING I OVERVIEW Motivation and Goals The most common type of genetic engineering in biotech uses recombinant DNA technologies to transfer genetic information from one organism to another for a potentially useful purpose. For example in agriculture there is now the possibility of new breeds of plants and animals. In medicine there is also help for people with genetic diseases. Genes have now been identified that are involved in Huntington s disease cystic fibrosis sickle-cell anemia retinoblastoma and Alzheimer s disease. Also in medicine the manufacturing of useful proteins through genetic engineering is a basic goal of many biotech firms. There is growing interest in
