Question

Which of the following statements about mitosis are true? Select all that apply

Two genetically identical daughter cells are formed.

It consists of two divisions.

Mitosis occurs in all body cells except gametes (sex cells).

The chromosome number in the resulting cells is identical to the parent cell.

DNA replication is completed before the cell divides

Mitosis occurs in only gametes (sex cells)

The chromosome number in the resulting cells is halved.

Answer 1

Option (1), (3), (4) and (5).

Step-by-step explanation:

Mitosis may be defined as a type of cell division by which the cell multiply their number. The four stages of mitosis are prophase, metaphase, anaphase and telophase.

Two daughter cells are produced from the parent cell by the process of mitosis. The chromosome number remains same in the daughter cells and the cells are almost identical to the parent cell. Single division is involved in mitosis. Mitosis occurs in the somatic cells of the body and meiosis occurs in the gametic cells. The DNA replication occurs in the synthesis phase and completes before the cell division.

Thus, the correct answer is option (1), (3), (4) and (5).

Answer 2

First what is mitosis?

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

According to definition,

• Two genetically identical daughter cells are formed. True.
• It consists of two divisions. False.
• Mitosis occurs in all body cells except gametes (sex cells). True.
• The chromosome number in the resulting cells is identical to the parent cell. True.
• DNA replication is completed before the cell divides. True.
• Mitosis occurs in only gametes (sex cells) . False.
• The chromosome number in the resulting cells is halved. False.
