Introduction

Science and cloning. Why are researchers and scientists so interested in cloning? The main view on cloning is that it is morally wrong and it is interfering with the very thing that has made life possible, although the reasons behind wanting to clone such large animals as sheep is not just to make a copy. Scientists claim that cloning an animal would be directly connected to there work aimed at producing medicines in the milk of animals. Researchers have actually managed to transfer human genes that produce useful proteins into large animals like sheep and cows, so that they also produce these useful proteins. Scientists claim that if an animal has these human genes then they can treat conditions like hemophilia and cystic fibrosis as well as other lung conditions. ...read more.

Middle

Dolly the sheep. Dolly the sheep may be the worlds most famous clone but surprisingly she was not the first. Cloning is basically a process which leads to an end product of a genetically identical copy of an animal. The animals cloned before dolly included a frog, sheep, mouse and cows. Taking a cutting of a plant in your garden and putting it in rooting powder then placing it back into the garden is also producing a clone. Human identical twins could also be known as clones. As we have just discovered that dolly was not the first animal to be cloned and of course looks just like any other sheep then why did we hear most about her and why was there so much concern? ...read more.

Conclusion

The scientists then injected the egg into an unfertilized egg cell which had had its nucleus removed then they made the two component part fuse by using electrical pulses. The unfertilized egg cell cam from a Scottish black faced ewe. After the procedure was completed then the scientists had to make sure that the resulting cell would develop into an embryo. The scientists then cultured it for about a week to see if it would divide and develop normally, before implanting it into the surrogate mother, another Scottish blackface ewe. The astonishing fact was that from 277 cell fusions, 29 early embryos developed and were implanted into 13 surrogate mothers. But only one pregnancy went to full term, and the 6.6kg Finn Dorset lamb 6LLS (alias Dolly) was born after 148 days. ...read more.

    The cloning of Dolly.

    proportion of the embryos thus far produced by nuclear transfer have become live offspring. What are Designer babies? A designer baby is made using the same method as Dolly the sheep; by emptying a human cell of its entire DNA.

  2. patterns of growth and development

    It takes a lot of practice before it becomes automatic to be able to do it. The legs of a new born baby need to have time for further growth and development before they are able to walk. Muscles such as the legs, hips and back need to strengthen.
