  1. The Perfect Copy

  2. What is cloning • to make an exact copy of a plant or animal by taking a cell from it and developing it artificially • Reproductive Cloning • DNA Cloning • Embryo Cloning

  3. Dolly was the first cloned mammal created by a Scottish scientist and his group in 1996. Dolly was world famous because she was exactly the same as her mother, in appearance and in genes. She died in 2003 because of lung disease. Dolly the sheep

  4. Dolly and its creator

  5. IdahoGem,the world's first cloned mule, was born on May 4. He is an identical genetic copy of his brother, a champion racing mule called Taz, and the first clone to be born in the equine family.

  6. copycat The world's first cloned kitten, named Cc. It was created by scientists in Texas using a cell taken from an adult tortoiseshell female (see next picture). The photo, taken on December 22 2001 when the kitten was seven weeks old, was made public in February 2002. donor Rainbow, the adult tortoiseshell female from which Cc was cloned. The nuclear-donor cat was used in the transfer technique pioneered by the Edinburgh scientists who made Dolly the sheep. The move opens the prospect of people being able to clone their pets.

  7. Five cloned female piglets, named Noel, Angel, Star, Joy and Mary - an important step towards "knock-out pigs". They were born on Christmas Day 2001. It is said to be a major step towards successfully producing animal organs and cells for use in human transplants.

  8. A pair of new-born cloned calves in a cowshed in Japan, on July 5 1998. They were born exactly two years after Dolly. They are the second adult-animal clones, and were produced by a similar technique. A spokesman for the research centre said the new technique would be used to breed better cattle strains with higher-quality beef or greater milk capacity.

  9. ANDi, the first genetically modified monkey, at the Oregon regional primate research centre in Oregon, USA. The birth of ANDi, the first monkey cloned by embryo splitting, is another incremental step toward designing and perfecting new treatments for human genetic disorders.

  10. Can you identify the differences between the cloned animals and normal ones? • The cloned animals or plants are exactly the same as the original ones.

  11. Do you think it would be a good idea to clone humans some day? • If possible, do you want another person to be exactly the same as you?

  12. Find the reasons why people are pro- or anti-cloning in the article and write them in the table below. C 2 Pro-cloning Anti-cloning 1 produce valuable tissues and organs that could be used to save human lives 1 may produce a real-life Frankenstein’s monster 2 create more disease in the animal world cure diseases like cancer 2 3 help those who are unable to have children 3 cloning shows no respect for human life 4 help those who want to clone their dead loved ones 4 would no longer be unique 5 fail to reduce Earth’s population
