Whether you're interested in cloning budgies or building black holes, the "How to" guides tell everything the reader needs to know. These hands-on guides provide step-by step instructions on how to build a Moon rocket, clone a sheep, split the atom or make a time machine. And on the way to becoming a time traveller or nuclear genius, you can learn about the brilliant scientists who first made these discoveries - and about the slightly less brilliant scientists who didn't. This book is a guide to genetics. In July 1995, a lamb was born in a shed in Scotland. This was a very special lamb. She was called Dolly, and she was an exact copy, or clone, of another sheep. For the first time in history, scientists had successfully cloned an animal! Learn the full story of Dolly and how she was born in "How to Clone a Sheep". The reader can also find out how to build a model cell, copy some DNA, and how to clone plants and animals at home!
