In a typical eukaryotic cell, where does mitosis (division of the genetic material) occur?

• A. In the mitochondria
• B. In the cytosol
• C. In the rough endoplasmic reticulum
• D. In the nucleus

Answer: (D)

Verified step by step guidance

1. Understand that mitosis is the process of division of the genetic material (chromosomes) in a eukaryotic cell.
2. Recall that eukaryotic cells have a defined nucleus where the cell's DNA is stored and organized into chromosomes.
3. Recognize that mitosis involves the replication and separation of these chromosomes to ensure each daughter cell receives an identical set of genetic material.
4. Identify that mitochondria and the cytosol are not the locations where the chromosomes are housed or divided during mitosis.
5. Conclude that mitosis occurs in the nucleus because it is the compartment containing the genetic material that must be divided.
