What is mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

How many chromosomes do fruit fly body cells have?

Back

Fruit fly body cells have 8 chromosomes.

Front

What is the result of mitosis in terms of chromosome number?

Back

After mitosis, each daughter cell will have the same number of chromosomes as the parent cell, which is 8 for fruit flies.

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is to ensure that each daughter cell receives an exact copy of the parent cell's genetic material.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the spindle apparatus starts to form.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

Why is DNA replication important before mitosis?

Back

DNA replication is important before mitosis to ensure that each daughter cell receives an identical set of genetic information.

Front

What is the role of the spindle apparatus in mitosis?

Back

The spindle apparatus helps to separate the chromosomes during mitosis by attaching to the centromeres and pulling the sister chromatids apart.
