In the case of Hua Hua and Zhong Zhong, researchers used modern technology developed only in the last couple of years to enhance the technique used to clone Dolly, which is called somatic cell transfer, or SCNT. (cmaaa.co.za)
The SCNT technique has worked to create about 20 different animals including frogs, mice, rabbits, pigs, cows and even dogs, but there have been 'numerous attempts to clone non-human primate species, but they all failed,' said Mumming Poo, an author on the paper. (cmaaa.co.za)

The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
Thus, the clone would be genetically identical to the nucleus donor only if the egg came from the same donor or from her maternal line. (who.int)
