“12th Class Biology Chapter 23 Quiz: Biotechnology” is a very fast-advancing field that combines biological sciences with technology to come up with innovative solutions in health care, agriculture, and environmental management. Biotechnology is the use of living organisms, cells, or biological systems to make products or services. This chapter discusses the principles of biotechnology, techniques such as genetic engineering, cloning, and gene therapy, and the ethical concerns surrounding biotechnological applications. Strengthen your understanding with our MDCAT Quiz and free flashcards designed to help reinforce your knowledge and perform well in your exams.
Principles of Biotechnology
Biotechnology operates on several foundational principles drawn from biology, chemistry, and engineering. At its core, biotechnology involves manipulating biological systems or organisms to produce useful products. Some of the key principles include:
Genetic Engineering: This is the alteration of the genetic material of an organism to bring out desired characteristics. Through techniques like DNA recombinant technology, scientists can insert genes from one organism into another, thereby creating genetically modified organisms, or GMOs.
Fermentation: A metabolic process applied to the manufacture of substances such as alcohol, antibiotics, and enzymes by microorganisms such as bacteria and yeast.
Bioprocessing: The application of living cells or enzymes performing chemical reactions useful in an industrial context, from the production of insulin to that of biofuels.
These principles are the foundation of the different applications of biotechnology in medicine, agriculture, and industry.
Ethical Issues in Biotechnology
While biotechnology brings along many advantages, it also raises ethical concerns, especially on issues of gene manipulation and GMOs. Problems such as how safe GMOs are in the environment, issues of designer babies, and access to biotechnology in developing countries have been widely debated. Ethical guidelines and regulations are critical to ensure the responsible use of biotechnological advances.
