Animal cloning is the process of creating an identical copy of a living organism. It is used in medical research to develop animal models of human diseases, allowing the study of biological interactions and testing new treatments before human application. Cloning can also be used to produce genetically modified animals for therapeutic proteins or beneficial food components. It also contributes to preserving endangered species and restoring genetic diversity. Despite scientific benefits, cloning raises ethical and legal issues, requiring strict regulations to ensure responsible and safe use, along with ongoing research to understand long-term effects.
