The part of the cell cycle that processes by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus is known as Mitosis. Thus, the correct option for this question is B.
The cell cycle may be defined as the entire sequence of events that may happen from the end of one nuclear division to the beginning of the next. The complete cell cycle is divided into two phases. They are as follows;
During interphase, the cell prepares for division by increasing its size and replicating genetic material. While the M phase involves the division of the cell nucleus. By the M phase, chromosomes present in the nucleus are separated into two daughter nuclei which leads to the formation of genetically identical daughter cells.
Therefore, the correct option for this question is B.
