CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The rate at which a particular type of cell divides is linked to the body’s need for that cell type. Skin cells are typically exposed to more damaging conditions than are liver cells. Skin cells must be replaced more often than liver cells. Therefore, which of these statements is true?
A
Skin cells and liver cells divide at the same rate.
B
Liver cells divide more often than skin cells.
C
Skin cells divide more often than liver cells.
D
Neither skin cells nor liver cells divide.
Explanation: 

Detailed explanation-1: -Consider the following information: The rate at which a particular cell divides is linked to the body’s need for that cells type. Skin cells are typically exposed to more damaging conditions than are liver cells. Skin cells must be replaced more often than liver cells.

Detailed explanation-2: -Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.

Detailed explanation-3: -Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Detailed explanation-4: -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-5: -The form of cell division known as mitosis is responsible for the body’s expansion and repair. Gametes are created as a result of the cell division process known as meiosis.
