Listening activity

Gapfill exercise

Cloning is the process of a genetically identical copy of an organism. Researchers have been experimenting with cloning since the 1900s, when they attempted to create genetic copies of animal embryos. As became more advanced, it became possible to make clones of fully-grown creatures. The first successful cloning of an adult organism was in 1996, when a British group managed to produce a cloned sheep. The sheep’s name was Dolly, and she lived for six years. Scientists have since managed to clone many other types of animals. In fact, there are now that offer expensive pet cloning services. The idea of human cloning has come up in scientific , but many people have ethical concerns about the consequences. Because of this, human cloning is illegal in several countries.
