What process involves cell division where the nucleus divides into nuclei with the same number of chromosomes?

• A. Meiosis
• B. Binary Fission
• C. Mitosis
• D. Bud Development

Answer: (C)

The process that involves cell division where the nucleus divides into two nuclei containing the same number of chromosomes is known as mitosis. During mitosis, a single cell's nucleus divides to form two daughter nuclei that are genetically identical to the original nucleus, ensuring that each daughter cell receives an identical set of chromosomes.

This process is crucial for growth, development, and tissue repair in multicellular organisms. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase, each characterized by specific events that ensure the accurate distribution of chromosomes. The outcome is typically two diploid daughter cells in organisms that reproduce sexually, maintaining the chromosome number of the parent cell.

Understanding this process is fundamental in biology, as it underpins cellular reproduction and is distinct from other forms of cell division.
