Mitosis Quiz

1. What happens during prophase in the cell cycle?

The chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear membran breaks down. This is the longest phase.

The chromosomes line up at the center of the cell during prophase.

The cytoplasm divides, separating the cell into two daughter cells.

The cell prepares for division by duplicating its DNA.

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, centrioles move to opposite poles, spindle fibers form, and the nuclear envelope breaks down. This stage is crucial for preparing the cell for division.

Explanation

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, centrioles move to opposite poles, spindle fibers form, and the nuclear envelope breaks down. This stage is crucial for preparing the cell for division.

2. What happens during Metaphase in cell division?

Second step. The chromosomes line up in the center of the cell. Each chromosome is connected to a spindle fiber at the centromere.

Final step where cell completes its division

First step where chromosomes condense

Stage where cells divide into two daughter cells

Metaphase is the stage where chromosomes align in the center of the cell, ready to be separated into two daughter cells. It is a crucial step in ensuring the accurate distribution of genetic material during cell division.

Explanation

Metaphase is the stage where chromosomes align in the center of the cell, ready to be separated into two daughter cells. It is a crucial step in ensuring the accurate distribution of genetic material during cell division.

3. What happens during telophase?

The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear membranes form.

The chromosomes align along the cell's equator.

The chromosomes condense and become visible under a microscope.

The cell begins to divide into two daughter cells.

Telophase is the final stage of mitosis where the chromosomes move to opposite ends of the cell, preparing for cell division. This is when two new nuclear membranes form around each set of chromosomes, leading to the formation of two separate nuclei.

Explanation

Telophase is the final stage of mitosis where the chromosomes move to opposite ends of the cell, preparing for cell division. This is when two new nuclear membranes form around each set of chromosomes, leading to the formation of two separate nuclei.

4. What is cytokinesis?

The cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes.

The deletion of excess genetic material within the cell.

A stage in the cell cycle where DNA replication occurs.

A process where cells merge together to form a single entity.

Cytokinesis is the process of dividing the cytoplasm to form two daughter cells, each with a complete set of chromosomes. It is distinct from other stages in the cell cycle such as DNA replication or cellular merging.

Explanation

Cytokinesis is the process of dividing the cytoplasm to form two daughter cells, each with a complete set of chromosomes. It is distinct from other stages in the cell cycle such as DNA replication or cellular merging.

5. What occurs during the interphase of the cell cycle?

The cell grows and replicates its DNA and centrioles.

The cell divides into two daughter cells.

The cell performs protein synthesis.

The cell undergoes apoptosis.

Interphase is a phase of the cell cycle where the cell grows, replicates its DNA, and prepares for cell division. It is a period of high metabolic activity and is crucial for the cell to progress through the cell cycle.

Explanation

Interphase is a phase of the cell cycle where the cell grows, replicates its DNA, and prepares for cell division. It is a period of high metabolic activity and is crucial for the cell to progress through the cell cycle.
