By: Olga Sobolevskaya, 15 years ago the world learned about the
appearance of the first cloned mammal – Dolly the sheep. At that moment the cloned lamb created by Scottish bioengineers was seven months old. However, scientists were not in a hurry to announce the sensation because there had been too many failures before. Today cloning remains a difficult task and is still unsafe, experts say.Mammals that are born in the usual way, as a result of natural reproduction, combine the mother’s and father’s genes. Dolly, whose life evolved from a mature body cell, rather than a sex cell, only inherited the genetic information of the prototype sheep. In the last 15 years a whole army of cloned animals has been bred – from cats to mules – and large bioengineering centres function in many countries of the world. One of such well-known Russian centres is located in Pushchino, a science-town near Moscow Source: Voice of Russia.
