Dolly (5 July 1996 – 14 February 2003) was a female Finn-Dorset sheep and the first mammal that was cloned from an adult somatic cell. She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland .

This can result in a low percentage of successfully reprogrammed cells. For example, in 1996 Dolly the sheep was born after 277 eggs were used for SCNT, which created 29 viable embryos, giving it a measly 0.3% efficiency. [40] Only three of these embryos survived until birth, and only one survived to adulthood. [30]
Dolly was formed by taking a cell from the udder of her 6-year-old biological mother. [30] Dolly's embryo was created by taking the cell and inserting it into a sheep ovum. It took 435 attempts before an embryo was successful. [31] The embryo was then placed inside a female sheep that went through a normal pregnancy. [32]
In 1997, scientists successfully cloned a sheep and named the animal Dolly after country legend Dolly Parton — for a very specific reason.. The "Jolene" singer, 78, spoke to The Guardianfor a ...
Nuclear transfer is a delicate process that is a major hurdle in the development of cloning technology. [5] Materials used in this procedure are a microscope, a holding pipette (small vacuum) to keep the oocyte in place, and a micropipette (hair-thin needle) capable of extracting the nucleus of a cell using a vacuum.
A guest on Antiques Roadshow left expert Cristian Beadman stunned by bringing in Dolly the sheep’s fleece for valuation. Dolly, the first mammal that was cloned from an adult somatic cell, was ...
With the cloning of a sheep known as Dolly in 1996 by somatic cell nuclear transfer (SCNT), the idea of human cloning became a hot debate topic. [5] Many nations outlawed it, while a few scientists promised to make a clone within the next few years. The first hybrid human clone was created in November 1998, by Advanced Cell Technology.
