Cloning

From Animals to Humans: is it safe?

History

Cloning is when you extract an organisms DNA and you insert the DNA into a female egg cell. Once it is fertilized by a sperm cell it grows into an exact replica of the organism that the DNA was extracted from. The main cause of cloning is to repopulate extinct or endangered species. The first cloned organism was a sheep named Dolly. Although she looked the same she didn't live as long as the original species.

Cloning Humans

There are still many questions about cloning humans. For example if it is an overall safe thing to do. Or if the life expectancy is the same as the average human.
