The way it works is first you take out a cell from either a part of the body or a fertilized egg . Then you take that cell and put it in to a unfertilized ovum .

这种方法的过程是首先从身体部分或受精卵中取出一个细胞，然后把它 放到 未 受精 的 卵细胞中。

When the cell starts to split you take out the cell and replace it into another unfertilized ovum .

当细胞开始分裂时，取出细胞并把它放到另一个 未 受精 的 卵 细胞中。
