What is the primary purpose of mitosis in eukaryotic cells?

• A. To synthesize proteins required for cell function
• B. To produce two genetically identical daughter cells for growth and tissue repair
• C. To generate gametes with half the number of chromosomes
• D. To increase genetic diversity through recombination

Answer: (B)

Verified step by step guidance

1. Understand the context of the question: Mitosis is a process of cell division in eukaryotic cells. It is distinct from meiosis, which is involved in the production of gametes (sperm and egg cells).
2. Recall the primary purpose of mitosis: It is to ensure that a single parent cell divides to produce two genetically identical daughter cells. This is crucial for growth, tissue repair, and maintaining genetic consistency.
3. Eliminate incorrect options: The synthesis of proteins is not the primary purpose of mitosis, as this occurs during other phases of the cell cycle (e.g., G1 and G2 phases). Similarly, generating gametes and increasing genetic diversity are functions of meiosis, not mitosis.
4. Focus on the correct answer: The correct purpose of mitosis is to produce two genetically identical daughter cells, which are essential for growth and tissue repair in multicellular organisms.
5. Summarize the distinction: Mitosis ensures genetic stability and is involved in somatic cell division, while meiosis is specialized for sexual reproduction and genetic diversity.
