That's not quite right. Mitosis is the process of cell division that results in two daughter cells that are genetically identical to the parent cell.

While organelles do replicate during the cell cycle, this is a separate process that happens alongside mitosis. Here's a breakdown:

* Mitosis is the division of the nucleus and the chromosomes within. This ensures that each new cell receives a complete set of genetic material.

* Organelle replication occurs throughout the cell cycle, including during interphase (the period between mitotic divisions). This is how the cell builds up its internal machinery.

So, while organelle replication is essential for cell function and happens alongside mitosis, mitosis itself specifically refers to the division of the nucleus.
