1) GMOs are organisms that have had their DNA altered for purposes like research, producing animal proteins, correcting genetic defects, and improving plants and animals.
2) One method for creating GMOs involves using Agrobacterium tumefaciens bacteria to transfer desired genes into plant cells through wounds in the plant. The transferred DNA then integrates into the plant's chromosome.
3) While GMOs could help increase crop yields to feed a growing population, there are also health and environmental concerns about long-term impacts of GMOs that require more research.
