>>14Well as for telomere extension, I'm honestly unsure as to the effect of telomerase within the oocyte cytoplasm in somatic cell nuclear transfer (SCNT). Though, I guess it would work. Either way, you basically get a clone. As for wiping epigenetic imprints and mutations (Single nucleotide polymorphisms frame shifts and all that), I doubt they could fix mutatons accquired during life.
I bet that if they did single cell transcriptone analysis that you wouldn't get the same genome in each cell in an individual due to mutations anyway (Of course exlcuding cells like gametes, red blood cells, some cardiomyocytes etc since they are haploid or have no nucleus, binucleate etc). They are taking one single cell's nucleus... you don't know the variation that mutations brought compared to lets say the original zygote during fertilization. Although cells do have gene repair mechanisms so I'd guess it would generally be a "clone".
As for clones, I guess it depends what context everyone is talking about. If I remember correctly, China is starting to clone animals for food. In the lab context, SCNT is quite commonly done I believe, though it is tightly regulated for human cloning, not sure about other animals, don't think so though. Even then, SCNT has challenges with the inheritance of maternal mitochondria too, since we all inherit our maternal mitochondria from the oocyte not from our fathers, putting another animals nucleus with different mitochondria may have an effect, though mitochondria have their own genome, you never know.
>>16 I don't think clones are created sterile, they should be able to reproduce if no complications arise. I think you are thinking of mules etc, mixed animals which are usually if not all sterile.
