NEET BIOLOGY

Detailed explanation-1: -In closed mitosis, the daughter chromosomes migrate to opposite poles of the nucleus, which then divides in two.

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: -In meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four daughter cells, each with half the number of chromosomes as the parent cell. The first separates homologs, and the second-like mitosis-separates chromatids into individual chromosomes.

Detailed explanation-4: -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. When mitosis is not regulated correctly, health problems such as cancer can result.

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.
