Dolly The SheepDolly The Sheep

Hello Dolly

Dolly was the first

mammal cloned from an

adult cell.

She was born in 1996

and died in 2003.

She was 6 when she

died, about half the usual

age for a sheep

From National Geographic

Scientists in Texas have successfully cloned a cat,

opening the way to replicating pets and other

valued animals once the technique is perfected.

The kitten, called CC (the old typist's abbreviationfor carbon copy) and now almost two months old,

appears healthy and energetic, although she is

completely unlike her tabby surrogate mother, Mark

Westhusin and colleagues at Texas A&M University,College Station, announce in the February 21 issue

ofNature.

A country use cloning to culture the a

species of tomato. This clone species

widely use throughout the country

because there are big and have goodtaste. Government urge all farmer to

grow this species of tomato and

prevent other tomato species to beplant. Do you agree with this

decision???

30 Cloned Human Embryos

U.S. and South Korean scientists have cloned 30

human embryos. They said that this is a 'major step

forward' in curing currently incurable diseases. The

thirty human embryos each contain stem cells that

can be used to create almost any human tissue.Diseases such as diabetes and muscular dystrophy

damage this tissue.
