The unique cloned macaque ReTro celebrated its second birthday

The rhesus macaque has a DNA set 93% identical to human DNA, so the genetic engineering experiments with these animals serve as a basis for working with humans in the future. And it is already clear how difficult this process will be, and therefore the appearance of human clones should not be expected soon. Since the appearance of the famous Dolly the sheep, three decades have passed, many clones of different creatures have been created, but this area of science is still full of complexities and mysteries.
