Cloning 



                              Clones

Hey everybody the bestscienceblog12 here and today I will be talking about clones and animals that have been cloned. Clones are organisms that share the exact same genetic material. A clone would look exactly like you but depending on its environment it would pick up a different personality and actions.

Animals that have been cloned include sheep, buffalo, monkeys, African Wildcats, carp, mice cows, and many more.

One of the most famous clones is Dolly the Sheep. Dolly was made from a single piece of DNA but three female sheep helped make her. Dolly was made when scientists took one egg cell and extracted the nucleus from that cell. Then they proceeded to take a cell sample from the udder of a second sheep. Using tiny needles they injected the DNA from the first sheep into the egg cell of the second sheep. Finally this new egg cell is put into the uterus of the third sheep.


Dolly died at the age of six which is very young for a sheep. She also developed Arthritis. Arthritis is an inflammation of one or more joints.

Cloning will also bring the possibility of cloning extinct animals like saber-tooth tigers.

Many people have different views on cloning. The goods effects of cloning include being able to give people that can't have children be able to have some and people can make their babies look the way they want to. The bad effects are that people think others are acting like god playing with the human race. Many people also think this is un-ethical.
