Cell Division

Front

What is the importance of replicating DNA before a cell divides in mitosis?

Back

To ensure that each daughter cell receives the full amount of DNA.

Front

In which phase does DNA condense into rod-like structures called chromosomes?

Back

Prophase.

Front

What are the structures that hold together sister chromatids?

Back

Centromeres.

Front

After mitosis, how do the two resulting cells compare to the starting cell?

Back

They are identical to the starting cell and identical to each other.

Front

What is the process by which the DNA and nucleus are divided into two new nuclei?

Back

Mitosis.

Front

What are chromosomes?

Back

Structures made of DNA that contain genetic information.

Front

What is the role of centromeres during cell division?

Back

They hold sister chromatids together and play a crucial role in their separation.

Front

What happens during prophase of mitosis?

Back

Chromatin condenses into chromosomes, and the nuclear envelope begins to break down.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

Front

What is the significance of spindle fibers in mitosis?

Back

They help separate the sister chromatids and pull them to opposite poles of the cell.
