Dolly's debut set off a firestorm about both the practical value and ethics of cloning, including the possibility of human cloning. (pewresearch.org)
The Court disagreed, stating that 'Dolly herself is an exact genetic replica of another sheep and does not possess 'markedly different characteristics from any [farm animals] found in nature,'' and thus, 'Dolly's genetic identity to her donor parent renders her unpatentable. (patentdocs.org)
In Dolly's case, the cell came from the mammary gland of an adult ewe. (eurostemcell.org)
The year after Dolly's creation, U.S. President Bill Clinton imposed a ban on the use of federal funds for human cloning but stopped short of banning all cloning research. (wgnradio.com)
Dolly's creation showed that genes in the nucleus of a mature cell are still capable of reverting to an embryonic totipotent state - that is, the cell can divide to produce all of an animal's differential cells. (worldtimetodays.com)

A blastocyst (cloned or not), because it lacks any trace of a nervous system, has no capacity for suffering or conscious experience in any form - the special properties that, in our view, spell the difference between biological tissue and a human life worthy of respect and rights. (wikiquote.org)
To produce Dolly, the cloned blastocyst was transferred into the womb of a recipient ewe, where it developed and when born quickly became the world's most famous lamb. (eurostemcell.org)

if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (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)
The somatic cell nuclear transfer (SCNT) technique being discussed in the story is the same process that made Dolly the sheep. (humanize.today)
Because cattle are a species widely used for nuclear transfer studies, and more laboratories have succeeded in cloning cattle than any other specie, this review will be focused on somatic cell cloning of cattle. (biomedcentral.com)
