Animal Cloning

Biotechnology use in animal cloning

What is cloning?

Biochemistry definition of cloning: replicate (a fragment of DNA placed in an organism) so that there is enough to analyze or use in protein production.

In animal cloning:

Basically this means that cloning is using biotechnology and biochemistry to recreate an animal exactly like the first being duplicated.

how it works

Reproductive cloning happens when researchers remove a mature somatic cell, such as skin cell from the animal in which they want to clone. Then from there they transfer DNA

of the donors animal somatic cell into an egg cell, or oocyte that has had its own DNA-containing nucleus removed.

Who discovered cloning

Hans Spemann envisioned cloning and permitted that animals could be cloned. But It took a team effort to successfully clone an animal and many scientist had trial and errors before they were successful in animal cloning.

When and where the first successful cloning of an animal was

The first animal cloned was a sheep, named Dolly. The cloning was on July 5th 1996. she was cloned in the Roslin institute located in Midlothian, Scotland. Dolly was born on February 22,1997 and died February 14,2003 and lived to be 6 years old.

The big Debate

Many people still debate whether cloning animals should be legal. These are some pros and cons of the issue.


  • Animal cloning can be beneficial to farmers because they can produce more dairy products such as milk and cheese along with providing more food such as meat to sell.
  • Biotechnology also helps scientist advance in the science feild.


  • Animal cloning can be dangerous to the animals and possibly the food and milk they produce.
  • many people are against animal cloning because they say it is against nature.
