Cloned Monkeys: A Gene Technology Breakthrough

The Success and Challenges of Cloning Mammalian Animals

In 1996, researchers achieved a groundbreaking feat when they successfully cloned Dolly the Sheep using a technology called somatic cell cloning or somatic cell nuclear transfer. Since then, this technology has been tested on 20 other mammalian species, with varying levels of success. However, cloned animals often suffer from organ and muscle damage, which significantly reduces their life expectancy. Among the different species, cows have shown the best chances of survival, while primates have had the lowest success rates.
