In Japan, was born bull clone, At used for insemination, which is a die 15 years ago.
The birth of the “copies” animals whose tissue is saved more than a decade at a temperature of 80 degrees Celsius below zero was first proved resistance genetic material that is located in the cell.
The experiment showed that it is possible to save the tissue of animals threatened with eradication to be in the future this kind of re-restored to life.
Cloning is carried out by a group of scientists from the Institute for zoo research in Gifu, on the island of Honshu.
Clone bull was born in July 2008. from cells of Jusufuku, bull died of age in September 1993.
He was known for that is significantly contributed to the extraordinary selection of cattle meat.
Scientists are keep his testicles in the aluminum box and keep them ten years frozen to minus 80 degrees Celsius.
Then they have three years to keep the temperature even lower liquid nitrogen (minus 196 degrees).
