Cloning animals through somatic cell nuclear transfer has potential advantages and disadvantages. The advantages include having an endless supply of food animals that could be cloned from previous animals. The most famous example of animal cloning was Dolly the sheep, the first mammal cloned from an adult somatic cell. However, many cloned animals die before birth or are born alive but with serious abnormalities. Those that survive often have premature deaths or high birth weights. The process of cloning is also inefficient.

coined the word "clone" during a speech in 1963. In 1966,
scientists Marshall Niremberg, Heinrich Mathaei, and Severo
Ochoa broke the genetic code, allowing for studies on genetic
engineering. The first gene was isolated in 1969 and the first
recombinant DNA molecules, a combination of the DNA from
two different organisms, were created in 1972. In 1977, a
German biologist created mice with a single parent. By 1979,
Karl Illmensee claimed to have successfully cloned three mice.
HISTORY

10. ADVANTAGES
There will be an endless supply
of animals to clone, and we will
never run out of food from
animals, because we have been
able to clone based on previous
efforts, the most famous of these
was the first ever cloning of an
animal, Dolly the lamb which
was a successful cloning where
Dolly was a healthy lamb.
