Recombinant DNA technology involves combining genetic material from different sources to create new DNA molecules. It offers numerous applications in fields such as medicine, agriculture, and biotechnology.
Key Components and Processes
- Restriction enzymes:Cut DNA at specific sequences.
- DNA ligase:Joins DNA fragments together.
- Plasmids:Small, circular DNA molecules used as vectors to carry foreign DNA.
- Host organisms:Bacteria or yeast that replicate and express recombinant DNA.
Applications
- Production of therapeutic proteins (e.g., insulin, growth hormone)
- Development of genetically modified crops (e.g., pest resistance, drought tolerance)
- Creation of diagnostic tools (e.g., DNA fingerprinting, genetic testing)
Creating Useful Products Using Recombinant DNA Technology
