A [[somatic cell]] is a regular body cell, not an [[egg cell]]. The [[nucleus]] of the somatic cell was removed and put into an unfertilised [[egg cell]]. The process is called [[somatic cell nuclear transfer]].<ref>{{Cite journal|author=McLaren A |title=Cloning: pathways to a pluripotent future |journal=Science |volume=288 |issue=5472 |pages=1775–80 |year=2000 |pmid=10877698 |doi=10.1126/science.288.5472.1775|s2cid=44320353 }}</ref><ref name=Wilmut>{{Cite journal|author=Wilmut I  |display-authors = etal |title=Viable offspring derived from fetal and adult mammalian cells |journal=Nature |volume=385 |issue=6619 |pages=810–3 |year=1997 |pmid=9039911 | doi=10.1038/385810a0 |bibcode=1997Natur.385..810W|s2cid = 4260518 }}</ref>  She was cloned at the [[Roslin Institute]] in [[Edinburgh]], [[Scotland]].

The cell used as the donor for the cloning of Nam was taken from a [[mammary gland]]. The production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual. She was cloned so she did not need any male cells to fertilize the egg and mature it. She only has one parent.
