Dolly is the first mammal to be cloned from an adult cell and this made her the world’s most famous clone. A clone has the same DNA sequence as its parent and therefore, it is genetically identical. Researchers claimed that they had used a mammary gland cell for cloning Dolly.
In the previous attempts at cloning of animals such as frogs, mice, and cows, DNA from embryos had been used.
Dolly was cloned at the Roslin Institute in Scotland and lived there until her death in 2003 at the age of six.
