The first cloned mammal, Dolly the ewe was born on July 1996 at the Roslin Research Institute, in Roslin, Scotland with assistance from biotechnology company PPL Therapeutics. Tee process was led by Ian Wilmut who obtained a nucleus from a mammary cell of an adult ewe transplanting it into an enucleated egg extracted from a second ewe. The nucleus was fused with the new host by administering electrical pulses making the egg divide and develop into an embryo, which was implanted into a surrogate mother ewe to gestate normally. Dolly was the genetic twin of the donated mammary cell nucleus.
