Question

HOW DOES THE NUCLEUS IN A CELL FROM THE EMBRYO DIFFER FROM THE NUCLEUS REMOVED FROM THE EGG

Answer 1

The genetic material of the donor egg cell is removed and discarded, leaving it 'deprogrammed.' What is left is a somatic cell and an enucleated egg cell. These are then fused by inserting the somatic cell into the 'empty' ovum. After being inserted into the egg, the somatic cell nucleus is reprogrammed by its host egg cell. The ovum, now containing the somatic cell's nucleus, is stimulated with a shock and will begin to divide.

Answer 2

The nucleus is removed from an unfertilised egg cell. the nucleus from an adult body cell, such as a skin cell, is inserted into the egg cell. an electric shock stimulates the egg cell to divide to form an embryo. these embryo cells contain the same genetic information as the adult skin cell.
