Study Notes
Introduction to Biotechnology
- Biotechnology involves the use of biological systems, living organisms, or derivatives thereof, to make or modify products for specific use
- Products of biotechnology range from agricultural products (genetically modified foods), pharmaceutical and medicinal products (vaccines and monoclonal antibodies), industrial raw materials (synthetic raw materials), and military products (bio-hazard weapons)
Areas of Biotechnology
- White Biotechnology: Industrial Biotechnology, primarily bio-catalysis and the production of chemicals/materials from renewable resources, as well as (hazardous) waste treatment
- Red Biotechnology: Medical and pharmaceutical biotechnology
- Green Biotechnology: Agricultural biotechnology, primarily genetic engineering of plants
- Blue Biotechnology: Marine and aquatic applications of biotechnology, e.g. fish farming and algae cultivation
- Grey Biotechnology: Conservation and restoration of contaminated natural ecosystems
- Gold Biotechnology: Also known as bioinformatics; responsible for obtaining, storing, analyzing, and separating biological information, especially that related to DNA and amino acid sequences
Timeline of Biotechnology
- Ancient Biotechnology: Early history as related to food and shelter, includes domestication
- Classical Biotechnology: Built on ancient biotechnology; fermentation promoted food production and medicine
- Modern Biotechnology: Manipulates genetic information in organisms, genetic engineering
Types and Applications of Biotechnology
- Microbial Biotechnology
- Agricultural Biotechnology
- Animal Biotechnology
- Forensic Biotechnology
- Bioremediation
- Aquatic Biotechnology
- Medical Biotechnology
- Pharmaceutical Biotechnology
Pharmaceutical Biotechnology
- Biopharmaceutical drugs generated through researches in cell biology, genetics, and recombinant DNA technology
- Recombinant DNA (rDNA) and monoclonal antibody (mAb) provide exciting opportunities for new pharmaceuticals development as well as new approaches to drug delivery
Advantages of Biotechnology
- Allows us to create waste products with better biodegradable properties
- Helps us minimize or eliminate waste products
- Enables us to manage landfills more effectively
- Reduces infectious disease rates
- Helps us create vaccines and treatments that reduce difficult symptoms of disease
Cons of Biotechnology
- Creates an all-or-nothing approach
- Lack of genetic diversity due to processes that increase crop yields and improve medical science
- Field of research with many unknowns
- Can ruin croplands and reduce their viability
- Can be used for destruction, e.g., weaponizing crops and diseases
Basic Tools and Techniques Used in Biotechnology
- Recombinant DNA Technology (RDT, Genetic Engineering)
- Enzymes: cleaving enzymes, synthesizing enzymes, joining enzymes, alkaline phosphatases
- Vector or Vehicle DNA: plasmids, bacteriophage DNA, cosmid, phagemid/phasmid, artificial chromosome vectors
- Passenger DNA: complementary DNA- cDNA, Synthetic DNA- sDNA, random DNA
Enzymes Used in Recombinant DNA Technology
- DNA ligase: joins DNA fragments with cloning vector
- Reverse transcriptase: synthesizes complementary strand (cDNA) from mRNA template
- Restriction endonuclease: recognizes and cuts DNA strand at specific sequence called restriction site
- Terminal transferase: converts blunt end of DNA fragments into sticky end
- DNA polymerase: synthesizes new DNA strand
