Graphic Overview of the Process of Nuclear Transfer

Why is the resting state so important?

  Test tubes The removed cells were cultivated , or kept alive, in a laboratory dish . Then the researchers reduced the nourishment they had been giving these cells. The cells went into a resting state , like a coma . This was the key step. In the resting state, the specific genetic instructions in operation in the cells were erased. Each cell contained a full set of genes, but no specific genes were turned on. In other words, they were now prepared to divide more cells that could specialize anew, into any kind of cell.
