Question: how does cloning work??

Tiffany Taylor answered on 13 Jun 2012:

Cloning is just copying something exactly. You can clone a single bit of DNA (we do this all the time in the lab), bacteria reproduce by cloning because they don’t have sex they just make a copy of themselves, or some clever scientists have managed to artificially clone a whole animal (you might have heard of Dolly the sheep who was a clone). In fact, identical twins are also clones! Because they are genetically an identical copy of each other.

But to clone a whole animal first you get two cells, you remove the nucleus from one and stick in the nucleus from the other cell. You then shock it with a pulse of electricity and insert it into the womb of a female. And voilà, a clone is born. (It’s a bit more complicated than that, but it’s the gist – don’t try it at home).
