...ion. This can be accomplished through somatic cell nuclear transfer or "therapeutic cloning." Here, you take an unfertilized egg, and remove the nucleus. Then, you inject the DNA-containing nucleus from an adult cell, say a skin cell, into the egg and allow it to grow into an embryo. Once it reaches the blas...Scientists take a step nearer to creating an artificial egg using a somatic cell
