Biotechnology and Genetic Modification | IGCSE and O Level Biology pptx
This presentation explores the fascinating fields of biotechnology and genetic engineering. It begins with practical applications of biotechnology, such as using bacteria to produce foods like yoghurt, biofuels through yeast fermentation, and enhancing bread-making and fruit juice production by employing specific enzymes like pectinase. The use of biological washing powders and the production of lactose-free milk by adding lactase further highlight biotechnology’s role in everyday life. The presentation then delves into genetic engineering, explaining how recombinant DNA is created by inserting, modifying, or removing genes—illustrated by examples like bacteria engineered to produce human insulin and genetically modified crops (e.g., Golden Rice) for improved nutrition and pest resistance.
