Respuesta :
The cell duplicates its chromosomes before dividing D. So each daughter cell will receive a full set of DNA.
If the cell were to divide without duplicating its chromosomes, the daughter cells would only receive half of the genetic information from their parents, and thus wouldn't be able to function correctly with only half of a genome. Additionally, you can confirm that the answer is D because the other answers are incorrect. If a cell duplicates before dividing, it will not become polyploid, this occurs with incorrect division, therefore answer A is incorrect. Answer B doesn't fit the question because not all daughter cells are genetically different from their parent cells (mitosis requires duplication but creates identical offspring). Finally, Answer C is incorrect because each daughter cell doesn't receive a duplicate set of DNA in mitosis, the parent cell physically splits itself into two (two daughter cells are created in place of the parent cell).
Hope this helps!
