Cell Division | MCQs

Explanation

• Cytophase is not a stage of mitosis.

The stages of mitosis are:

1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Explanation

Explanation

Mitosis Stages:

Karyokinesis: Division of the nucleus (prophase, metaphase, anaphase, telophase).

Cytokinesis: Division of the cytoplasm (occurs after karyokinesis).

Explanation

The cell cycle is also known as the cell division cycle.

It is the sequence of changes that occurs between one cell division and the next.

Explanation

The centromere is the region where the two chromatids (sister chromatids) are attached to each other.

It serves as a constricted region that holds the chromatids together until they separate during cell division.

Explanation

Chromosomes are thread-like structures that appear during cell division, specifically during the prophase stage of mitosis or meiosis.

They are made up of condensed chromatin and carry genetic information from one generation of cells to the next.

Explanation

Mitosis is a type of cell division that involves the replication of a cell's DNA and the division of the cell into two daughter cells. It is essential for:

• Growth: Mitosis allows an organism to grow and develop by increasing the number of cells.
• Repair: Mitosis helps replace damaged or dead cells with new ones.
• Asexual reproduction: Mitosis enables asexual reproduction, where an organism produces offspring that are genetically identical to the parent.

Explanation

The form of cell division known as mitosis is responsible for the body's expansion and repair.

while

Gametes are created as a result of the cell division process known as meiosis.

Explanation

• Meiosis is a type of cell division that produces four non-identical daughter cells, each with half the number of chromosomes as the parent cell.
• This process is essential for sexual reproduction, as it allows for the mixing of genetic material from two parents and the creation of genetically diverse offspring.

Explanation

• Mitosis is a process of cell division that results in the production of two daughter cells, each with the same number of chromosomes as the parent cell.
• This process is essential for growth, repair, and asexual reproduction in living organisms.
