When a researcher transplanted the nucleus of an intestinal cell from a tadpole into an egg cell whose nucleus had been destroyed, the egg developed into a normal frog. this illustrates that (a) a nucleus that is removed from its normal location is influenced by adjoining cells.(b) the homeobox genes in a transplanted nucleus undergo mutation.(c) each cell of an organism has all the genes needed for development.(d) genes are gained during the process of differentiation.(e) scientists can clone a human by putting one of his or her nuclei into an egg cell.

(C) each cell of an organism has all the genes needed for development.

Explanation:

According to my research on studies conducted on Genetics, I can say that based on the information provided within the question this illustrates that each cell of an organism has all the genes needed for development. If this were not the case then the frog would either not be born or would be born with serious abnormalities because the cell did not have the necessary genes needed for the frog to form correctly.

I hope this answered your question. If you have any more questions feel free to ask away at .
