The following question confused me at first

enter image description here

However, I presumed that it must be in comparison to meiosis. In that case D would be correct.

However, the correct answer is A.

How can this be? I know that in mitosis it is the chromatids that are 'pulled away' to opposite poles. In meiosis, this is whole chromatids but anaphase still occurs.

I suspect I don't understand the question. Where have I gone wrong in my reasoning?


Cell cycle can be divided into two phases:

1. Interphase

2. M-phase(Mitotic phase)

Note: M-phase can also mean Meiotic phase but it is not the full form of the acronym.

So M-phase in mitosis has four phases:

  • Prophase
  • Metaphase
  • Anaphase(your answer)
  • Telophase

A mitotic cycle:


The rest of the options:

B. Cytokinesis

Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.

Your question doesn't seem to consider cytokinesis as a part of M-phase (i.e to be occurring during the late karyokinesis). So it has to be ruled out.(Making some assumptions as this is a key to reaching the single correct answer in MCQs, if not this would have had two right answers.)

C. DNA replication - happens in S-phase of interphase

D. Interphase (certainly not the one)
