Question: What Was Important About Dolly The Sheep?

How did Dolly change the world?

TWENTY years ago Dolly the sheep, the first animal clone, was revealed to the world. She caused a sensation. Many scientists had believed cloning animals was impossible. Dolly’s creation showed that DNA in a differentiated cell could be repurposed through nuclear transfer, opening up two new possibilities.

Why was Dolly the sheep such a big accomplishment?

Dolly was remarkable in being the first mammal to be cloned from an adult cell. This was a major scientific achievement as it demonstrated that the DNA from adult cells, despite having specialized as one particular type of cell, can be used to create an entire organism.

What impact did the cloning of Dolly of have on society?

Dolly’s birth proved that scientists could turn back the clock on a fully developed adult cell to make it behave like a cell from a newly fertilised embryo and this encouraged researchers in Edinburgh and across the world to investigate other techniques to reprogram adult cells, ultimately leading to the discovery of

What are the risks of cloning?

Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.

Why was the cloning of Dolly such a monumental step?

Dolly was such as monumental step because it was the first time a mammal had successfully been cloned and survived, although Dolly had some poor health conditions. I feel as though therapeutic cloning is more acceptable because it is creating stem cells and not a whole new person.
