NEET BIOLOGY

Detailed explanation-1: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.

Detailed explanation-2: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.

Detailed explanation-3: -During cell division, the nucleus divides first and then the cytoplasm. The process of nuclear division is called karyokinesis while the process of cytoplasmic division is called cytokinesis.

Detailed explanation-4: -The large central nucleolus, which occupies about 20% of the nuclear volume, persists throughout the cell cycle. At mitosis, the nucleolus divides and moves to the poles in association with the chromosomes. The structure of the mitotic spindle and its relationship to the nucleolus are unknown.

Detailed explanation-5: -In order for your cells to reproduce they must be capable of dividing into new cells. This means they must be able to divide the nucleus. This occurs during a process called mitosis. Mitosis is the process of splitting the cell’s genetic material into two new nuclei.
