Question

Which stages of cell division do the following figures A and B represent, respectively?

• A. Metaphase, Telophase
• B. Telophase, Metaphase
• C. Late Anaphase, Prophase
• D. Prophase, Anaphase

Answer 1

The correct option is C Late Anaphase, Prophase

Figure A represents anaphase, in which the sister chromatids of each chromosome separate and begin moving to opposite ends (poles) of the cell. Spindle fibres which are not connected to chromatids, lengthen and elongate the cell. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Figure B represents prophase. Centrioles move to the opposite sides of the nucleus. Chromosomes start to thicken and shorten.
Metaphase is the second stage of cell division between prophase and anaphase during which the chromosomes become attached to the spindle fibres.
Telophase is 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.
