Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does mitosis do?
A
regulates the cell cycle
B
promotes spindle formation
C
suppresses cancer
D
results in the division of two genetically identical nuclei
Explanation: 

Detailed explanation-1: -Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell’s nucleus is split into two equal sets of chromosomes.

Detailed explanation-2: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. Your body contains trillions of cells (thousands of millions).

Detailed explanation-3: -During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

Detailed explanation-4: -Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus.

Detailed explanation-5: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
