Which process marks the end of mitosis where the cell membrane begins to pinch or a new cell wall forms?

• A. Metaphase
• B. Telophase
• C. Prophase
• D. Interphase

Answer: (B)

The process that marks the end of mitosis where the cell membrane begins to pinch or a new cell wall forms is telophase. During this final stage of mitosis, the chromosomes that were separated during anaphase begin to de-condense back into their chromatin form, and nuclear envelopes re-form around each set of chromosomes at the poles of the cell. In animal cells, the cytoplasm begins to pinch inward along the metaphase plate, resulting in cytokinesis, which completes the separation of the two daughter cells. In plant cells, a cell plate forms at the center, which develops into a new cell wall, effectively splitting the cell into two distinct daughter cells. This transition into the final stages of cell division is critical for ensuring that each daughter cell has the appropriate genetic material and cellular components necessary for functioning.
