Question

Select the correct option with respect to mitosis:

• A. Chromosomes move to the spindle equator and get aligned along equatorial plate in metaphase
• B. Chromatids separate but remain in the centre of the cell in anaphase
• C. Chromatids start moving towards opposite poles in telophase
• D. Golgi complex and endoplasmic reticulum are still visible at the end of prophase

Answer 1

The correct option is A Chromosomes move to the spindle equator and get aligned along equatorial plate in metaphase

During metaphase which is the second stage of mitosis, the chromosomes, guided by the spindle fibres, line up in the middle of the dividing cell along the equatorial plate.
Anaphase is the third stage of cell division, between metaphase and telophase, during which the chromosomes move away from one another to opposite poles of the cell.
Telophase the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
During prophase, which is the first phase, the nuclear envelope starts to dissociate into small vesicles. The membranous organelles (such as the Golgi apparatus and endoplasmic reticulum) fragment and disperse toward the periphery of the cell.
