Explanation: 

Detailed explanation-1: -You will remove the nucleus from the egg cell using a blunt pipette and a sharp pipette. The blunt pipette will hold the egg cell in place while the sharp pipette goes into the cell and sucks out the nucleus (chromosomes). This is called enucleation. The nucleus is then discarded.

Detailed explanation-3: -The egg cell has had its nucleus removed so that it will read and duplicate the DNA of the donor cell.

Detailed explanation-4: -The blunt pipette held the somatic cell. The sharp pipette sucked out the nucleus and then inserted it into the enucleated egg cell.

Detailed explanation-5: -They write new content and verify and edit content received from contributors. nuclear transfer, the introduction of the nucleus from a cell into an enucleated egg cell (an egg cell that has had its own nucleus removed).
