DOLLY AND BEYOND
Ever wished as a young kid that your best toy was duplicated so that if one of them broke, you would have another one? Well, scientists have cloned the most famous clone: Dolly the sheep.
On February 22, 1997, scientists at the Roslin Institute in Edinburgh, Scotland announced that they had cloned a sheep called Dolly. What they really did was the first cloning from an adult mammal. Do you know what we're saying? Well, we will explain it.
What the scientists did was that they took a mammary (Of or relating to a breast or milk-producing organ) cell from a sheep and put it into a egg. Then, they let the egg grow into an embryo (an organism in its early stages of development), and then the fused embryo was transplanted into a ewe (female sheep). They did this in January 1996.
On July 5 at 4:00 PM, Dolly was born. She was born in a shed down the road from the institute. She was in good condition and weighed 14 1/2 lbs. The scientist that was given credit of the birth of Dolly is 52-year-old embryologist Dr. Ian Wilmut.
Some graduate students at the Roslin Institute did most of the labor work and did not receive much credit.
