If a fully differentiated mammary gland cell were to divide, what type of cell would you expect to be produced?
Papessa [141]

1. The cells would be for repair.

2. Cells grown in serum free or reduced medium are termed donor cells starved. It is done by biologist to synchronize all the cells in same phase of cell cycle.

3.In the egg containing the donated somatic cell is reprogrammed by host machinery. The enucleated egg incorporated with somatic cell nucleus is given an electric shock. The cell becomes viable ready to divide and produce a viable organism.

After continuous mitotic divisions, cell becomes blastocyst.
