Question

The diagram given alongside represents a stage of mitosis.

1. Identify the stage of cell division.
2. Name the parts labelled A and B.
3. What is the unique feature observed in this stage?
4. How many daughter cells are formed from this type of cell division?

Answer 1

1. Anaphase
2. A: Spindle fibre
   B: Centromere
3. 1. Separation of sister chromatids at the centromere region.
   2. Migration of chromosomes toward opposite poles due to the shortening of spindle fibres.
   3. Formation of a cleavage furrow/constriction in the plasma membrane (indicative of late anaphase initiating cytokinesis).
4. Exactly two genetically identical daughter cells are formed at the end of mitotic cell division.
