Study Notes
Gene Knockout
- Gene knockout is a technique used to disrupt a gene in an animal
- Researchers observe the effects of the disrupted gene on the animal
- By observing the effects, researchers can determine the role and function of the gene
- Gene knockout studies in rats and mice can provide insights into gene function in humans
- Humans share similarities with these animals
- Gene knockout studies may lead to a better understanding of gene function in humans
