Answer / Vikash Kushwaha
A transgenic animal is a genetically modified organism that has had foreign DNA artificially inserted into its genome. A transgenic knockout mouse, specifically, refers to a type of transgenic animal in which a specific gene has been removed or "knocked out." Advantages of using transgenic animals for neuroscientific studies include: 1) Manipulating specific genes to study their functions and interactions; 2) Creating models of human diseases for research purposes. Disadvantages include potential limitations in accurately mimicking human genetic conditions and the ethical concerns associated with modifying living organisms."
"One example is the creation of a transgenic mouse with a knocked-out gene responsible for Alzheimer's disease to study the progression and potential treatments for the disease. Another example is using zebrafish as a model organism for neurodevelopmental disorders, such as Huntington's disease.
