A copying machine for living beings?

Without any doubt, if there had been elections for the animal of the year 1997,

Dolly would have been the winner! Dolly is a Scottish sheep that you see in the

5 photo. But Dolly is not just a simple sheep She is a clone of another sheep. A clone means: a copy. Cloning means copying "from a single master copy. Scientists

succeeded in creating a sheep (Dolly) that 10 is identical to a sheep that functioned as a master copy

It was the Scottish scientist Ian Wilmut who designed the copying machine for sheep. He took a very small piece from the 15 udder of an adult sheep (sheep 1).

From that small piece he removed the nucleus, then he transferred the nucleus

into the egg-cell of another (female) sheep (sheep 2). But first he removed from that

20 egg-cell all the material that would have determined sheep 2 characteristics in a lamb produced from that egg-cell, lan Wilmut implanted the manipulated egg-

cell of sheep 2 into yet another (female) 25 sheep (sheep 3), Sheep 3 became pregnant and had a lamb: Dolly.

Some scientists think that within a few years it will be possible to clone people as well. But many governments have already 30 decided to forbid cloning of people by law. Which sheep is Dolly identical to?

A Sheep 1

B Sheep 2

C Sheep 3
