Pišemo test iz biologije in jaz si ne morem in ne morem zapomnit, iz kere ovce so kaj vzel in kam dal, a je pravilno, da so iz ovce A vzeli jedro telesne celice in ga dali v prazno telesno celico ovce B? Ali je obratno? A sploh dajo to celico v uno?

She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte (developing egg cell) that has had its cell nucleus removed. The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother.[9] Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal.[10] Dolly's existence was announced to the public on 22 February 1997.[
pri kloniranju so namreč uporabili celico mlečne žleze. Kloniranje je bilo izvedeno tako, da je bilo jedro celice darovalke prenešeno v jajčece, ki mu je bilo jedro predhodno odstranjeno. Donorsko celico so odvzeli šestletni ovci. Iz jajčeca z donorskim jedrom se je nato razvil zarodek.
