Although Dolly was born in 1996, the scientists at Roslin institute disclosed the matter only on 22 February 1997. They waited several months to pile up the needed data and write down all the procedures they had to go through to make the cloning possible.
It was later published that the researchers got their much-awaited result after attempting for the 277 times. The researchers made a miracle happen which was a breakthrough in the history of cloning.
