Study Notes
Knock-in Mouse
- A genetically modified animal created by inserting a protein-coding cDNA sequence at a specific location on an organism's chromosome.
- Primary purpose: to create an animal with a modified or enhanced-function allele.
- Involves the insertion of a specific gene sequence at a targeted location on a chromosome.
