Read the following statements regarding the events of karyokinesis in mitosis and select the incorrect one.

Options

  1. AThe centrosome, which had undergone duplication during S phase, begins to move towards opposite poles during p
  2. BThe morphology of chromosomes is most easily studied during metaphase.
  3. CDuring anaphase, the centromere of each chromosome is directed towards the equator with the arms trailing behi
  4. DNucleolus, Golgi complex and endoplasmic reticulum reform during telophase.

Correct answer

C. During anaphase, the centromere of each chromosome is directed towards the equator with the arms trailing behi

Step-by-step solution

During anaphase, the sister chromatids separate and move towards the opposite poles. As each chromosome moves away from the equatorial plate, the centromere of each chromosome remains directed towards the pole (leading edge), with the arms of the chromosome trailing behind. Therefore, the statement that the centromere is directed towards the equator is incorrect. Answer: During anaphase, the centromere of each chromosome is directed towards the equator with the arms trailing behind.
