Tools and Techniques for Gene Cloning
- Three categories of tools: Instruments (devices), Biological tools, and Techniques
- Instruments include electrophoresis, PCR, spectroscopy, chromatography
- Biological tools: enzymes, cloning vectors, competent hosts

Biological Tools - Enzymes
- Restriction enzymes are molecular scissors that cut DNA at specific sequences
- Also called restriction endonucleases (REN) or restriction enzymes (RE)
- Serve as bacterial defense mechanism against viral DNA
