What are Zinc Finger Nucleases?
Zinc Finger Nucleases are engineered proteins that facilitate targeted gene editing by creating double-strand breaks in DNA.
Why are knockout rabbits important for research?
Knockout rabbits serve as valuable models for studying human diseases, particularly those related to cardiovascular health.
How does the microinjection process work?
Microinjection involves injecting ZFN RNA into the cytoplasm of embryos to induce genetic modifications.
What is the significance of using large animal models?
Large animal models better mimic human physiology, making them crucial for translational research.
Can this method be applied to other species?
Yes, the techniques used in this study can potentially be adapted for gene targeting in other large animals, such as pigs.
