Final answer:
Mitosis comes before cytokinesis in the cell cycle to ensure proper distribution of genetic material and the formation of two new cells.
Step-by-step explanation:
Cellular division consists of two main parts: mitosis and cytokinesis.
Mitosis is the division of the nucleus, while cytokinesis is the division of the cell into two new cells.
Mitosis comes before cytokinesis in the cell cycle because first, the nucleus needs to divide and ensure that each daughter cell receives a diploid number of chromosomes.
Then, cytokinesis occurs to complete the division of the cytoplasm, resulting in two genetically identical daughter cells. So, mitosis is necessary before cytokinesis to ensure proper distribution of genetic material and the formation of two new cells.
