Genetic engineering is also called genetic modification or GM. It involves modifying the genome of an organism by introducing a gene from another organism to result in a desired characteristic.
Genetic engineering involves these steps:
- selection of the desired characteristic
- the gene responsible for the characteristic is 'cut out' of the chromosome
- the gene is transferred and inserted into another organism
- replication of the modified organism.
Plant crops have been genetically engineered to be disease resistant or to produce bigger fruits.
