Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the purpose of mitosis?
A
To increase the surface area of a cell
B
To allow cells to divide for growth, repair, and renewal
C
For increasing genetic variation within a species
D
To allow for DNA replication and protein synthesis
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The aim of mitosis is to separate the genome and ensure that the two daughter cells inherit an equal and identical complement of chromosomes (Yanagida 2014).

Detailed explanation-3: -Only sexually reproductive organisms utilize meiosis. The role of the process is to produce sex cells and to repair genetic defects in germ line cells (the sex cells).

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. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.

Detailed explanation-5: -Therefore, oriented mitotic division of epithelial cells, especially ESCs, is particularly important for wound healing. The prolonged symmetric divisions of ESCs during early embryonic development generate large pools of stem cells for tissues repair in need.
