Detailed explanation-1: -Dolly was important because she was the first mammal to be cloned from an adult cell. Her birth proved that specialised cells could be used to create an exact copy of the animal they came from.
Detailed explanation-2: -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. Her cloning proved that a cloned organism could be produced from a mature cell from a specific body part. Contrary to popular belief, she was not the first animal to be cloned.
Detailed explanation-3: -By cloning a genetically modified cell using somatic cell nuclear transfer (SCNT). This was the method used to produce Dolly the Sheep, although she was not genetically modified as she was created using an unmodified cell.
