Biotechnology - 2 Biotechnology or genetic engineering has many goals, including: • Improving our understanding of inheritance and genetics with basic research • Improving our treatment of genetic disorders (and some diseases) • Using the tools of DNA technology to increase knowledge in all areas of biology • Facilitating forensics and criminal law by evidence analysis • Providing economic and health benefits in agriculture, medicine and elsewhere Some DNA technology research involves altering existing DNA to promote or prevent the expression of certain genes. One example of altered DNA is found in the commercial tomato industry. Biotechnology has been used to suppress the genes that promote ripening and softening of tomatoes so that tomatoes can stay on the plant longer (to develop the proper flavor), but not get soft. Firm tomatoes are necessary for transportation purposes. Many chemicals are now produced using strains of bacteria or fungi, genetically selected for their ability to produce quantities of the desired chemical, similar to
