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: -Mitosis is a type of cell division that occurs in almost all our cells and is necessary for our bodies to grow, develop and repair. During mitosis, two identical daughter cells are produced from a single cell. Page contents: From one cell to many.

Detailed explanation-3: -In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.

Detailed explanation-4: -In fact, interphase takes up about 90% of a cell’s life. That leaves just 10% for mitosis!

Interphase has three stages: G1, S and G2.

Detailed explanation-5: -The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell’s DNA, no genetic diversity is created through mitosis in normal healthy cells.
