प्रश्न
Mitosis is characterised by ______.
विकल्प
Reduction division
Equal division
Both reduction and equal division
Paining of homologous chromosomes
उत्तर
Mitosis is characterised by equal division.
Explanation:
Mitosis is the most dramatic period of the cell cycle, involving a major reorganisation of virtually all components of the cell. Since the number of chromosomes in the parent and progeny cells is the same, it is also called as equational division.
