Biology Mitosis Review

Front

What are spindle fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division. They are formed from microtubules and are created by centrioles.

Front

What is the role of centrioles in mitosis?

Back

Centrioles are organelles that help organize the assembly of spindle fibers during cell division.

Front

What are chromosomes?

Back

Chromosomes are long strands of DNA that contain genetic information. They become visible during cell division.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome that are connected by a centromere.

Front

What is a centromere?

Back

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

Front

What role do proteins play in cell division?

Back

Proteins help regulate the process of cell division by controlling the cell cycle and ensuring proper chromosome separation.

Front

What is the significance of the cleavage furrow?

Back

The cleavage furrow is the indentation that begins the process of cytokinesis, where the cell membrane pinches in to divide the cell into two.

Front

What happens during the Telophase (T) of mitosis?

Back

During Telophase, the chromosomes begin to de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the purpose of mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, allowing for growth and repair.

Front

What is cytokinesis?

Back

Cytokinesis is the final step of cell division, where the cytoplasm divides, resulting in two separate cells.
