 Nuclear transfer was the cloning technique used to produce the sheep Dolly. Which best describes nuclear transfer?

Apr 7th, 2015

Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte(unfertilized egg), and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state. If the cloned cells are placed in the uterus of a female mammal, a cloned organism develops to term in rare instances. This is how Dolly the Sheep and manyother species were cloned. Cows are commonly cloned to select those that have the best milk production.

Despite this, the low efficiency of the technique has prompted some researchers, notably Ian Wilmut, creator of Dolly the cloned sheep, to abandon it
