Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the purpose of the cell cycle?
A
To create new daughter cells
B
To prevent cancer from developing
C
To help the body fight viruses and bacteria
D
None of the above
Explanation: 

Detailed explanation-1: -The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

Detailed explanation-2: -This type of cell division not only allows the embryo and baby to grow, but it continues throughout life to repair the body or replace cells that have died. Unlike meiosis, the function of mitosis is to produce two identical daughter cells with exactly the same complement of chromosomes.

Detailed explanation-3: -Daughter cells made after mitosis are identical to each other, which helps grow and develop living organisms. Four daughter cells produced by meiosis are unique and have a half number of chromosomes than the parent cell. These are essential for sexual reproduction as they develop into egg and sperm cells.

Detailed explanation-4: -The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells.

Detailed explanation-5: -The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells.
