Which of the following is not a significant aspect of mitosis?
Options
- AIt introduce variations
- BIt replaces old or worn out cells
- CIt helps in healing wounds
- DIt maintains genetic stability
Correct answer
A. It introduce variations
Step-by-step solution
Mitosis is also called equational division because in this there is an equal distribution of chromosomes in daughter nuclei. It is also called somatic cell division. The number of chromosomes remains unchanged in mitosis, crossing over and recombination process is not seen in mitosis so, variation is not introduced through mitosis and it maintains genetic stability. It also helps in growth, repair, or healing by replacing old or worn-out cells by new cells.
