Cloning
Nature has been cloning organisms for
billions of years. For example, when a
strawberry plant sends out a runner
(a form of modified stem), a new plant
grows where the runner takes root.
That new plant is a clone.

Scientists have now managed to clone
animals by transplanting the genetic
information from a specialized cell
into an unfertilized egg cell whose
genetic information has been
destroyed or physically removed.

Since Dolly, several university laboratories
and companies have used various
modifications of the nuclear transfer
technique to produce cloned
mammals, including cows, pigs,
monkeys, mice and Noah.

The main reason to clone plants or
animals is to mass produce organisms
with desired qualities, such
as a prize-winning orchid or a
genetically engineered animal.

Other reasons for cloning might include
replacing lost limbs or deceased family pets
and repopulating endangered or even
extinct species.

Whatever the reasons,
the new cloning technologies have
sparked many ethical debates among
scientists, politicians and the general public.
Cloning: Yes or No?
1) Human Organs
2) Human Being (Complete)
3) Chickens for food
4) Cows for Milk
5) Really, really good teacher
6) Bacteria for medicine
7) Animal meat (without living animal)
8) Very Fast racehorse
