Cloning
by:Alan Cerda
Background info
Cloning is the process of copying one organism to make an exact copy. The first ever mammal to be cloned was Dolly, a sheep. Dolly was made in July 5, 1996. In order to make Dolly scientists used the cells of a Finn Dorset white sheep. Dolly was a big breakthrough in the science of cloning and now scientists are working to clone humans.
John Gurdon, Shoukhrat Mitalipov, Hans Adolf Edward Dreisch, Hans Spemann, etc. are people who contributed to the research and study of cloning. An example is when John Gurdon removed the nucleus of a fertilized egg cell and replaced it with a cell of a mature cell from a tadpoles intestine in 1962. The modified egg cell grew into a new frog showing that the mature cell still contained the genetic info needed to form all cell types. He contributed information needed for cloning.
Technology
Nuclear transfer is a laboratory procedure that removes the nucleus of a mature cell and places it into an immature female egg cell. The female cell, whose nucleus has been removed, can then reproduce. A benefit to cloning is that family pets or extinct creatures can be brought back to life. The risks are that species that are brought back to life may not be able to adapt to the new environment and the cloning could go wrong.
Some of the scientists that have helped in cloning.
Regulations
The government makes the laws and regulations for cloning. Some countries bann certain types of cloning. Some provide the funding for cloning. There are regulations against cloning because it's against some people's religions and some people are just against it. The government of a country has to pass laws for the regulations for cloning to be in place
