Miracle of Cloning

Science has been improved beyond our imagination. Cloning is one of the powerful inventions in science. Cloning is the creation of a living being that is an exact genetic copy of another. For example, each and every single bit of DNA is the same between the cloned sheep and the other sheep which has given the DNA. Tadpole was the first cloned animal in the year 1952. The test is carried out for many tadpoles but none of them had been survived to adulthood. There are three types of cloning. They are DNA cloning, Reproductive cloning and Therapeutic cloning. Our DNA is the most powerful one in the world. If all the DNA’s in our body are lined up, then it would reach to the sun and back more than 600 times.
