Answer:
Mitosis most directly plays a role in the division of a cell's nucleus.
Explanation:
As you may already know, mitosis is the cell division process, where a cell divides, giving rise to two cells equal to it. For this reason, we can say that mitosis plays a more direct role in dividing the nucleus of a cell.
Mitosis is extremely important for the physical development and growth of multicellular organisms. Through this process it is possible to perform regeneration processes of tissues essential for the life of organisms.
