Question

Nucleo-cytoplasmic ratio in eukaryotes is restored by

• A. meiosis
• B. mitosis
• C. both mitosis and meiosis
• D. neither mitosis nor meiosis

Answer 1

The correct option is B mitosis

Nucleo-cytoplasmic ratio in eukaryotes is restored by mitosis. As the cell grows, the cytoplasm content increases and thus the volume of cytoplasm is more than the nucleus. This disturbs the ratio in terms of volume between nucleus and cytoplasm. The nucleus is unable to control the activities of a large cytoplasm. Hence, the cell undergoes mitosis and forms two daughter cells to restore the nucleo-cytoplasmic ratio.

Meiosis usually occurs to form gametes that participate in sexual reproduction.
