It turns out that animal cloning experiments, which until recently seemed like science fiction, are approaching a critical statute of limitations. The cow, which was first cloned in Japan for the first time in the world 21 years ago, died due to natural aging.
This sad news was reported from Ishikawa Prefecture, where a significant experiment took place, resulting in the birth of the legendary twin calves Noto and Kaga. This happened according to the same technology by which the famous Dolly sheep was born. The expensive practice of obtaining clones has become successful and popular - by 2006, Japanese scientists were able to get fourteen cloned cows.
Kaga is considered the eldest of the clone sisters, and therefore the first. The youngest twin, Noro, died a year and a half ago, at an old age for the cow - she did not live a month before her twentieth birthday.
