Dolly the Sheep’s Fellow Clones, Enjoying Their Golden Years

Dolly the sheep was used for the study of cloning animals and whether if cloned animal would age prematurely. Scientists took a single adult cell, implanted into an egg cell where its own DNA was removed, and created an exact replica of its donor. Researchers explained that there were no abnormal deficiencies with the sheeps that were cloned but some appeared to show signs of osteoarthritis which Dolly was diagnosed with. Scientist declared that based on the new research cloning animals does not lead to the idea of premature aging.

Dolly, the cloned sheep

http://www.nytimes.com/2012/10/12/science/keith-campbell-cloner-of-dolly-the-sheep-dies-at-58.html?ref=biologyandbiochemistry
Keith Campbell, cell biologist, dies at the age of 58 in Derbyshire, a region of England.

Campbell was one of the most famous cell biologists because of his sheep, his cloned sheep that he created. This sheep became one of the most popular animals of all time because of the way it came to be. This idea of cloning brought upon two sides; the side for it which said this was something before deemed impossible and the scientists are overjoyed to see new work, and the other side which worried that next would be people being cloned. Campbell claimed that the greatest value of cloning lay in the potential to engineer animals to produce medications, and even transplantable organs, for use by human beings.

 

This is the picture of the famous cloned sheep, Dolly, who also normally reproduced 6 lambs. It took 277 attempts to create Dolly as the process was much moer vigorous and complex then a simple cutting as that of a plant. http://www.animalresearch.info/en/medical-advances/151/cloning-dolly-the-sheep/. In this website you can find how Dolly was cloned, what happened to her throughout her life, and the reason to clone sheep and other animals.

My personal opinion on this matter is a slight mix of both views. I feel as though it can and will have its benefits in the future but the fear of being able to clone humans is a very scary thought and needs to be taken into consideration before the idea of cloning begins to run rampant.

 

 

Russian scientists to attempt clone of woolly mammoth

This article is about the cloning of a woolly mammoth. Russian and Japaneses scientists are claiming that a thigh bone, that they found in August, contains remarkably preserved bone marrow cells. This bone marrow will be the first step in the cloning. The scientists believe that the cloning will be complete in the next five years.

The team is planning to extract a nucleus from the bone marrow and insert it into an egg from an African elephant. Similar procedures has been done before. In 2009 it was reported that the recently extinct Pyrenean ibex was bought back to life briefly after using 10 year old DNA from the animal's skin. The animal died after cloning due to breathing problems.

The Roslin Institute, famous for the cloning of Dolly the sheep, had some thoughts on the bringing back extinct animal to life. They believe that this is highly unlikely because of the use of the elephant as a surrogate mother. They suggested using a cow because it the best biological match but is too small compare to the woolly mammoth. They also doubt it because the scientists to successfully clone would need a whole cell. The Roslin Institute believe that the success rate for this experiment is 1-5%.
