What is the process of mitosis primarily responsible for?

• A. DNA replication
• B. Cell division
• C. Protein synthesis
• D. Energy production

Answer: (B)

Mitosis is a fundamental process in the cell cycle that is primarily responsible for cell division. During mitosis, a single cell divides to produce two genetically identical daughter cells, ensuring that each new cell receives an exact copy of the parent cell's DNA. This process is crucial for growth, development, tissue repair, and asexual reproduction in multicellular organisms. The stages of mitosis, which include prophase, metaphase, anaphase, and telophase, orchestrate the accurate separation of duplicated chromosomes into two separate nuclei. This careful choreography ensures genetic fidelity, allowing each daughter cell to function properly and maintain the organism's characteristics. While DNA replication occurs before mitosis during the S-phase of the cell cycle and is crucial for providing the genetic material needed for the daughter cells, it is not the focal point of mitosis itself. Protein synthesis and energy production are vital cellular processes, but they are distinct from the division of the cell that mitosis achieves. Thus, the primary role of mitosis is unequivocally cell division, enabling the continuity of life at the cellular level.
