China has used DNA to make a copy of a police dog famous for its abilities. The company that did the work hopes the clone will be as talented as the original dog, which they called the “Sherlock Holmes of police dogs”.
Every living thing has DNA – a special code that tells it how to grow. Usually an animal gets half of its DNA from its father, and the other half from its mother. Cloning is a complicated scientific process that uses the DNA of one living thing to create a new creature that is a copy of the original.
