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 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.

Detailed explanation-2: -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-3: -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-4: -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.

Detailed explanation-5: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
