Dolly Has Been Quietly Replicated into a Sheep Clone Army - Gearlog

Dolly Has Been Quietly Replicated into a Sheep Clone Army - Gearlog: "There's a public perception that cloned animals age prematurely, largely based on the untimely demise of Dolly. However, this may not be exactly accurate. According to Dr. Keith Campbell, one of the original Dolly scientists who also helped create this new generation, several cloned sheep have gone on to live (or are currently living) full sheepy lives well into their expected life spans.However, the general public remains largely unaware of these cases.

We've all heard how Dolly had truncated 'telomeres,' the little pieces of spare DNA on the end of chromosomes that grow shorter with age. The public perception is that these dwarfed telomeres are what led to Dolly's downfall. But the original research team would like to remind people that that Dolly came down with a lung infection, a common affliction among sheep living in closed quarters."
