12/3 Assign: Mitosis

Front

What is a chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What is mitosis?

Back

Mitosis is the process by which a multi-cellular organism replaces damaged body cells through cell division, resulting in two identical daughter cells.

Front

What are spindle fibers?

Back

Spindle fibers are protein structures that help separate sister chromatids during cell division.

Front

What happens during prophase?

Back

During prophase, the nuclear envelope disappears, chromosomes become visible, and microtubules form.

Front

What occurs during metaphase?

Back

During metaphase, spindle fibers attach to chromosomes, and centrioles line the chromosomes in the center of the cell.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

What is a centromere?

Back

A centromere is the region of a chromosome where two sister chromatids are joined together.

Front

What is the role of centrioles in cell division?

Back

Centrioles help organize the spindle fibers that separate chromosomes during cell division.

Front

What is anaphase?

Back

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

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 cell begins to divide.
