Understanding Biotechnology: Techniques and Applications in Genetics and Agriculture
Biotechnology encompasses various techniques that utilize living organisms to create products or services, including the alteration of genetic material in viruses, bacteria, plants, and animals. From ancient practices like selective breeding to modern applications in reproductive technology, biotechnology has evolved significantly. It has the potential to enhance food production, create new foods, and address health issues by treating diseases and preventing genetic disorders. This overview highlights the historical context and contemporary advancements in biotechnology.

Presentation Transcript
Biotechnology • Biotechnology refers to various techniques that use living organisms to make products or provide services. • It includes altering the normal genetic make-up of organisms, including viruses, bacteria, plants and animals.
Biotechnology Has Been Around Awhile • Breeding animals is an example of simple, less-sophisticated biotechnology that has been around for many years. • Selective breeding is when certain individuals with certain desirable traits are breed to produce offspring with similar traits.
Selective Breeding • Selective breading of animals was usually done by isolating a desirable male and female in a contained area during mating periods. • Selective breeding of plants was usually done through pollinating by hand. Desirable male gametes were manually brought into contact with desirable female gametes. • Female gametes were isolated from any other male gametes.
Biotechnology Through the Ages • Biotechnology dates back as far as 2000 B.C. • By selecting certain individual plants or animals with desirable characteristics to reproduce, farmers gradually create new genetic combinations over time.
Biotechnologies at Work • Yogurt and cheese are not naturally occurring foods. • They are produced with the help of bacteria and fungi that are not naturally found in them.
Today’s Biotechnology • With today’s knowledge in cell biology and DNA, biotechnology has specialized into a new area called reproductive technology. • Reproductive technology involves altering the genetic information in the cell’s nucleus to obtain favorable outcomes.
Reproductive Technology • Reproductive technologies hold the opportunity to: • increase the world’s food supply, • create new foods, • treat and cure various diseases, • prevent some inherited genetic disorders
