What Is Cloning and the History of Cloning

What is Cloning:

  • Cloning is the creating an organism that is an exact genetic copy of another, meaning every strand of DNA is the same between the two.
  • There are human clones that we see every day that have not been created in a lab, and they are what we call identical twins. Identical twins can be created naturally. 
  • The cloning that occurs in the labs can be created in five different ways: Recombinant DNA technology or DNA cloning, Reproductive Cloning, Therapeutic Cloning, Artificial Embryo Twinning and Somatic Cell Nuclear Transfer.

  • Cloning is not new to the world; it has been going on since the 1800s. Hans Dreisch, first cloned an embryo of a sea urchin. Then in 1970s, experiments on frogs, toads, plants, and animals were preformed. But experiments involving humans had never been tried until the sheep Dolly was born on July 6, 1996.
  • No one knows that scientists were cloning until the papers told the whole story about dolly and what the scientists had been up too. They told the paper that human cloning would occur. But no one knew how long it would take. They also did not know the medical problems, or risks that would occur after cloning an animal or human.
  • Cloning humans and animals is not the only type cloning that goes on in the labs; they are also working on cloning organs for organ transplants and stem cell for stem cell research.
