NEET 2002 Biology question

Nucleus of a donor embryonal cell/somatic cell is transferred to an enucleated egg cell. Then after the formation of organism, what shell be true : -

(1)Organism will have extranuclear genes of the donor cell
(2)Organism will have extra nuclear genes of recipient cellCorrect
(3)Organism will have extra nuclear genes of both donor and recipient cell
(4)Organism will have nuclear genes of recipient cell

Answer: (2)

Solution

In nuclear transfer cloning (as in Dolly), the nucleus of the donor somatic/embryonic cell is placed in an enucleated egg. The nuclear genes of the clone come from the donor nucleus, whereas the cytoplasm, including the extranuclear (mitochondrial) DNA, comes from the recipient egg
