Which process occurs during the M phase?

Which process occurs during the M phase?

• A. DNA replication
• B. RNA transcription
• C. Cytokinesis
• D. Mitosis and cell division

Answer: (D)

M phase is the part of the cell cycle when the cell divides. It includes both mitosis and cytokinesis. During mitosis, chromosomes condense, align, and are pulled apart into two new nuclei, while the nuclear envelopes reform around those separate chromosome sets. Cytokinesis then divides the cytoplasm, producing two distinct daughter cells. DNA replication happens earlier, in S phase, and RNA transcription is mainly a feature of interphase as the cell grows and prepares for division. So the process occurring during the M phase is mitosis and cell division.
