What is mitosis?

What is mitosis?

• A. The process where a cell divides to produce two genetically identical daughter cells
• B. The process of DNA replication
• C. The process of transcription
• D. The process of meiosis

Answer: (A)

Mitosis is the process by which a cell divides its nucleus to form two genetically identical daughter nuclei, setting the stage for a full cell division. During this step, replicated chromosomes (sister chromatids) are separated so each new nucleus gets a complete set of chromosomes. After mitosis, cytokinesis splits the cytoplasm, producing two separate genetically identical daughter cells. This is different from DNA replication, which occurs earlier in the cell cycle to duplicate the DNA; transcription, which makes RNA from DNA; and meiosis, which creates gametes with half the chromosome number and increases genetic variety. So the description that matches mitosis is the division of a cell to produce two genetically identical daughter cells.
