The M phase checkpoint ensures that all chromosomes are attached to the mitotic spindle. If this does not happen, cells would most likely be arrested in (D) metaphase.
So, the correct option is (D).
- Telophase the final stage of mitosis and the second division of meiosis in which the spindle vanishes and the nucleus reforms around each set of chromosomes.
- The prophase stage of mitosis and the mitotic division of meiosis is characterised by the condensation of two-chromatid chromosomes, the disappearance of the nucleolus and nuclear membrane, and the creation of the mitotic spindle.
- In G₂ phase the time in the cell cycle between the completion of DNA replication and the start of cell division – compare g1, m, and s phases.
- Metaphase is the third stage of mitosis, which is the process by which duplicated genetic material carried in the nucleus of a parent cell is separated into two identical daughter cells.
