In a typical eukaryotic cell, where does mitosis (nuclear division) occur?

• A. In the Golgi apparatus
• B. In the nucleus
• C. In the cytosol on free ribosomes
• D. In the mitochondrial matrix

Answer: (B)

Verified step by step guidance

1. Understand that mitosis is the process of nuclear division where the duplicated chromosomes are separated into two daughter nuclei.
2. Recall the structure of a eukaryotic cell, which includes the nucleus, cytosol, Golgi apparatus, and mitochondria, each with distinct functions.
3. Recognize that the nucleus is the organelle that contains the cell's genetic material (DNA) and is the site where chromosomes are organized and separated during mitosis.
4. Note that the Golgi apparatus is involved in modifying and packaging proteins, the cytosol is the fluid part of the cytoplasm where some metabolic reactions occur, and the mitochondrial matrix is the site of cellular respiration, none of which are involved in nuclear division.
5. Conclude that mitosis occurs in the nucleus because it involves the division of the cell's genetic material housed within this organelle.
