Study Notes
Overview of Cloning
- Cloning produces exact copies of cells, tissues, or entire organisms.
- Ian Wilmut and colleagues at the Roslin Institute in Edinburgh successfully cloned the first animal.
Dolly the Sheep
- Dolly, born on July 5, 1996, was the first mammal cloned from an adult somatic cell.
- The cloning process involved collecting a cell from the mammary gland of a Finn Dorsett sheep.
- An egg was sourced from a Scottish blackface ewe, and its nucleus was removed.
- The nucleus from the Finn Dorsett sheep's cell was inserted into the enucleated egg.
- The modified egg was implanted in the Scottish blackface ewe, leading to Dolly's birth.
Genetic Identity and Characteristics
- Dolly was genetically identical to the Finn Dorsett sheep, the source of the nucleus.
- She did not exhibit traits from the Scottish blackface ewe since her nuclear DNA originated entirely from the Finn Dorsett.
Life and Legacy
- Dolly lived a healthy life, producing several offspring through normal sexual reproduction.
- She passed away on February 14, 2003, due to a lung disease.
- Dolly's creation sparked numerous cloning attempts in mammals, but many clones face lethal conditions or severe abnormalities.
Broader Implications
- The cloning of Dolly raised ethical questions and concerns regarding cloning practices.
- Since Dolly, many cloned animals do not survive to birth or lead healthy lives, highlighting the challenges of cloning technology.
