Genetic Modification
The deliberate alteration of an organism's genetic material to achieve desired traits or characteristics through biotechnology.
Genetic Modification
Genetic modification (GM) represents a revolutionary advancement in biotechnology that allows scientists to directly manipulate an organism's DNA structure. This process involves inserting, deleting, or modifying specific genes to achieve desired outcomes.
Core Techniques
Gene Insertion
- Using vectors like plasmids or viruses
- CRISPR-Cas9 gene editing technology
- Particle bombardment methods
Gene Deletion
- Targeted removal of unwanted traits
- Knockout gene techniques
- selective breeding enhancement
Applications
Agricultural Uses
