Question

Which two processes occur during the M phase of the cell cycle?

• A. DNA replication and cell division
• B. Karyokinesis and cytokinesis
• C. Cell growth and karyokinesis
• D. Cytokinesis and DNA replication

Answer 1

The correct option is B

Karyokinesis and cytokinesis

The correct answer is b.

Explanation of correct answer:

1. During the M phase or mitotic phase, a cell divides into two daughter cells.
2. Nuclear division and cytoplasmic division takes place during the M phase, which is known as karyokinesis and cytokinesis, respectively.
3. During karyokinesis, there is division of the nucleus.
4. In cytokinesis, there is division of cytoplasm resulting in two daughter cells.

Final answer: Karyokinesis and cytokinesis occur during the M phase of the cell cycle.
