Nucleus of a donor embryonal cell/ somatic cell is transferred to...
Nucleus of a donor embryonal cell/ somatic cell is transferred to an enucleated egg cell. Then, after the formation of organism what will be true?
Options
- AOrganism will have extranuclear genes of the donor cell.
- BOrganism will have extra nuclear genes of the recipient cell.
- COrganism will have extra nuclear genes of both donor and recipient cells.
- DOrganism will have nuclear genes of the recipient cell.
Correct answer
B. Organism will have extra nuclear genes of the recipient cell.
Step-by-step solution
The organism will have extranuclear genes of recipient cell. Since the recipient cell has already been enucleated (its nucleus is removed), the organism developing from it would have the nuclear genes of donor cell.
Related Theory
The egg cell is enucleated, so the organism will only have extranuclear genes from it. These genes are present in chloroplast and mitochondria and are transmitted along the cytoplasm. This results in cytoplasmic or maternal inheritance.
