In which stage of mitotic cell division, chromosomes loose their identity?

Concept-

• Mitotic produced genetically identical cells, which are similar to the mother cells.
• Mitotic is also called equational division.
• Mitotic cell division is divided into the following four stages-
  • (a) Prophase  (b) Metaphase  (c) Anaphase  (d) Telophase

Explanation-

• At the beginning of the final stage of mitosis, i.e., telophase, the chromosomes that have reached their respective poles decondense and lose their individuality.
• The individual chromosomes can no longer be seen and chromatin material tends to collect in a mass in the two poles.
• This is the stage which shows the following key events-
  • Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements.

Hence in telophase, chromosome lost their identity.

Additional Information

• Mitosis or the equational division is usually restricted to the diploid cells only.
• Mitosis usually results in the production of diploid daughter cells with identical genetic complement.
• The growth of multicellular organisms is due to mitosis.
• A very significant contribution to mitosis is cell repair.
