Before egg fertilization, the gene produces a protein, found in the cytoplasm of the egg, that controls the pattern of cell division and thus handedness.

卵子受精之前，这种基因会产生一种蛋白质，这种蛋白质存在于卵子的细胞质中，它控制着细胞分裂的模式，从而控制着旋向性。

Dan and Scott Shillum are identical twins, genetic clones produced from the accidental division of a single fertilised egg into two embryos in their mother's womb some 40 years ago.

With only the genetic material from the person to be cloned inside the shell of the egg, the cell would be jolted with electricity to activate cell division.

The cell is then given a jolt of electricity to activate cell division, basically tricking the cell into doing what a fertilized egg would normally do.
