Cell Cycle & Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication. It consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

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).

Front

What occurs during G1 phase of the cell cycle?

Back

During G1 phase, the cell grows and carries out normal functions, preparing for DNA replication.

Front

What occurs during S phase of the cell cycle?

Back

During S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What occurs during G2 phase of the cell cycle?

Back

During G2 phase, the cell continues to grow and prepares for mitosis, including the synthesis of proteins necessary for cell division.

Front

What is mitosis?

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter nuclei.

Front

What are the stages of mitosis?

Back

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

Front

What happens during prophase of mitosis?

Back

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

Front

What happens during metaphase of mitosis?

Back

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

Front

What happens during anaphase of mitosis?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell as the spindle fibers shorten.
