- Dolly was the first mammal to be cloned from an adult somatic cell. She was born on July 5, 1996, at the Roslin Institute in Scotland.

- Dolly was cloned from a cell taken from the mammary gland of a six-year-old ewe. The cell was then fused with an egg that had had its nucleus removed, and the resulting embryo was implanted into a surrogate mother.

- Dolly's birth was a breakthrough in cloning technology. It showed that it was possible to create a viable animal from a single adult cell, and it opened up the possibility of cloning animals for a variety of purposes, such as meat production, organ transplantation, and endangered species conservation.

- Dolly lived for six and a half years. She was euthanized in 2003 after developing lung disease.

- Dolly's cloning has been the subject of much controversy. Some people believe that it is unethical to clone animals, and others worry about the potential risks associated with cloning technology. However, Dolly's birth also sparked a great deal of interest in cloning, and it has led to a number of important scientific advances.

- Dolly is now considered to be one of the most iconic animals in history. Her image has been used in countless books, articles, and documentaries, and she has become a symbol of the possibilities and challenges of cloning technology.
