Genetic Engineering
- Genetic engineering involves modifying an organism's genome by introducing a gene from another organism to achieve a desired characteristic.
- Example given: creating insect-resistant maize by introducing a gene from a soil bacterium that produces a natural insecticide.
- The process involves cutting out the desired gene from the donor organism (e.g., soil bacterium) and transferring it to the recipient organism's cell (e.g., maize).
- The modified cell is then used to grow a new plant, resulting in a genetically engineered variety with specific traits, such as insect resistance.
- Genetic engineering can also be used to produce larger and better-quality fruits.
- The key concept is that genes are extracted from one organism and inserted into another to impart desired traits.
