Topics in Biotechnology : Principles and Processes

1

1. Meaning and Principles of Biotechnology

  • Biotechnology is the use of living systems, cells, or enzymes to produce useful products and services.
  • Traditional biotechnology includes processes such as making curd, bread, and wine.
  • Modern biotechnology focuses on genetically modified organisms and molecular methods.

2. Restriction Enzymes and DNA Cutting

  • Restriction enzymes are molecular scissors used to cut DNA at specific locations.
  • They belong to a larger class of enzymes called nucleases.
  • Exonucleases remove nucleotides from the ends of DNA.
3

3. Separation of DNA Fragments by Gel Electrophoresis

  • Restriction digestion produces DNA fragments of different sizes.
  • DNA fragments are separated by gel electrophoresis.
  • DNA is negatively charged, so it moves toward the anode.

4. Cloning Vectors

  • Vectors carry foreign DNA into host cells and help it replicate.
  • Plasmids and bacteriophages can replicate independently inside bacterial cells.
  • Bacteriophages have very high copy numbers per bacterial cell.
