Learning Objectives

  • Biotechnology encompasses techniques that manipulate living organisms to produce useful products.

  • Tissue culture and somatic hybridization are pivotal in plant breeding and crop improvement.

  • Genetically Modified Organisms (GMOs) provide high-yield, stress-resistant crops while contributing to medical advancements through recombinant therapeutics.

Key Concepts

Genetically Modified Organisms (GMO)

Organisms whose genetic material has been altered through genetic engineering for desired traits.

Tissue Culture

The practice of growing cells or tissues in a controlled environment, leading to the development of whole plants from various plant parts.

Recombinant DNA Technology

A method used to combine DNA from two different sources, allowing for the production of new genetic material with desirable traits.

Transgenic Animals

Animals that have had their DNA manipulated to carry genes from other species, often used for research or production of biological products.

Gene Therapy

A treatment method that involves modifying genes to treat or prevent diseases, particularly genetic disorders.
