The cell cycle includes which processes?

• A. DNA replication, mitosis, cytokinesis
• B. Meiosis and fertilization
• C. Differentiation, apoptosis, necrosis
• D. Protein synthesis, transcription, translation

Answer: (A)

During the cell cycle, a cell grows, duplicates its DNA, and then divides into two new cells. DNA replication happens in the S phase so each daughter cell receives an identical copy. Mitosis follows, the process that splits the nucleus and distributes the duplicated DNA equally. Cytokinesis then divides the cytoplasm, resulting in two separate daughter cells. These steps together define the cell cycle. Meiosis and fertilization belong to sexual reproduction and are not part of the typical somatic cell cycle. Differentiation and cell death processes (apoptosis, necrosis) are outcomes that can occur during a cell’s life but are not stages of the cell cycle. Protein synthesis and its steps (transcription, translation) are ongoing cellular activities that occur throughout the cycle, not the defining sequence of the cycle.
