A wild Arctic wolf was successfully cloned for the first time in the world by a Beijing-based gene firm.
In 1996, Scottish scientists cloned the first animal, a sheep they named Dolly. She was cloned using an udder cell taken from an adult sheep.
What is Cloning?
There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning.
1. Gene cloning produces copies of genes or segments of DNA.
2. Reproductive cloning produces copies of whole animals.
3. Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Verifying, please be patient.
