Cell cycle and Mitosis

Front

What are spindle fibers?

Back

Spindle fibers are structures that help separate sister chromatids during cell division (mitosis) by attaching to the centromeres of chromosomes.

Front

What is the result of mitosis?

Back

Mitosis results in the formation of two identical cells, each with the same number of chromosomes as the original cell.

Front

List the stages of mitosis in order.

Back

The stages of mitosis in order are: prophase, metaphase, anaphase, and telophase.

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a chromosome, joined together at a region called the centromere.

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to allow cells to divide for growth, repair, and renewal.

Front

Define chromosomes.

Back

Chromosomes are long, thread-like structures made of DNA and proteins that contain genetic information.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during metaphase?

Back

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

Front

Describe anaphase.

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.
