Front

What is the cell cycle?

Back

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What happens during prophase of mitosis?

Back

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

What is metaphase in mitosis?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane.

What occurs during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

What happens in telophase?

Back

In telophase, the chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm divides, resulting in two separate daughter cells.

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes during mitosis by attaching to the centromeres and pulling them apart.
