The nuclear division in eukaryotic cells where each cell receives a copy of the original chromosomes is called mitosis.

Here's why:

* Mitosis is a process of cell division that results in two daughter cells that are genetically identical to the parent cell. This means they have the same number of chromosomes and the same genetic information.

* Meiosis, on the other hand, is a process of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.
