In lower animals such as amoeba, mitosis is a means of asexual reproduction without the involvement of sex cells or gametes. The term ‘mitosis’ was coined by Walther … WebThe stages of Mitosis are: Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.

WebAlthough there are 5 phases in mitosis, with the exception of the metaphase to anaphase transition, these phases are not discrete and happen as a continuous process. Prophase is the first stage in mitosis. The nuclear envelope begins to break down and chromosomes condense and are now visible.
