Dolly, the first clone of

a mammal

Cloning

Cloning is the creation of an organism that is an exact genetic copy of another orgaanism. It means that the DNA is the same between those organisms. Ever heard of Dolly? Dolly was the first clone of a mammal. Dolly's DNA came from a body cell from another sheep. Do you know how cloning is done? First, a donor cell is taken from a male. At the same time, an egg cell is taken from a female. Next, the nucleus of the egg cell is removed. Then, the two cells are combined by using an electric shock. Afterwards, the combined cell begins to divide. Finally, the embryo is put into a foster mother, and the baby will be born. This is how humans and animals get cloned. It is called nuclear transfer. Cloning can make organisms only have a head and still survive or not have a head but will still survive. It is very interesting. Do you support cloning? Cloning can save and produce many lives. Cloning can bring back endangered species. Right now, pandas are endangered. It is possible that they may be cloned by one of their close reletives to increase their population. Cloning can also bring back a parent or child. But, if you clone a parent, the parent will be younger than your own child! Cloning is not always the best thing to do. Cloning had made scientists think that they are God because they have the power to copy cells. Also, if the original has a disease, then the clone will also have the disease because a clone is an exact copy of the organism. If you clone, you will have a shorter lifespan. Scientists expected Dolly to have a lifespan of around eleven to twelve years, but Dolly lived up to only six years. Cloning has made many people wonder what the future uses of cloning will be like. Many people agree that scientists should understand more about cloning, then make decisions about how this technology should be used.

How Dolly got cloned

Some countries have banned cloning because they think that cloning is too advanced for them. At the same time, some countries allow cloning because they think cloning could save many lives. I personally think that cloning was one of the world's best inventions because it could save lives. God tells us to be fruitful and to increase in numbeer, so we must fulfull God's Will.
