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.
