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. When mitosis is not regulated correctly, health problems such as cancer can result.

Detailed explanation-2: -During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Detailed explanation-3: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.

Detailed explanation-4: -There are two types of cell division: mitosis and meiosis. These processes ensure that more cells in the body are created for growth, that old or dying cells are replaced, and that gametes can be created.

Detailed explanation-5: -Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
