Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows, synthesizes proteins, and prepares for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is a period of preparation for mitosis, where the cell continues to grow and produces proteins necessary for cell division.

Front

What are the main stages of mitosis?

Back

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

Front

What occurs during prophase?

Back

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

Front

What is the significance of metaphase in mitosis?

Back

In metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

What happens during anaphase?

Back

During anaphase, spindle fibers pull sister chromatids apart to opposite poles of the cell.

Front

What occurs during telophase?

Back

During telophase, the chromosomes de-condense, nuclear envelopes reform around each set of chromosomes, and the cell prepares to divide.

Front

What is cytokinesis?

Back

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