Introduction to Biotechnology

Introduction to Biotechnology

• Biotechnology is the use of biological agents (like microorganisms or cells) or their products (like enzymes) to create or modify products, solve problems, or make new discoveries.
• This field draws on various scientific disciplines including biology, chemistry, engineering, and computer science.
• Biotechnology applications span diverse areas, including medicine, agriculture, and industry.

Branches of Biotechnology

• Recombinant DNA technology: Manipulates DNA sequences to create new combinations of genes or insert genes from one organism into another.
• Genetic engineering: A subset focused on modifying the genes of organisms to change their traits or create new ones.
• Bioremediation: Uses biological systems to remove contaminants or pollutants from the environment.
• Immunotechnology: Focuses on the immune system for therapeutic applications, like vaccines and antibody treatments.
• Bioinformatics: Uses computational tools to analyze biological data and information.

Applications of Biotechnology in Medicine

• Drug discovery and development: Recombinant DNA technology is used to produce therapeutic proteins and hormones like insulin, growth hormone, and blood clotting factors.
• Gene therapy: Introduces functional genes to treat genetic disorders.
• Diagnostics: Uses biotechnology to develop tests for diseases and conditions, often based on genetic markers.
