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 (M).

Front

What occurs during the G1 phase of the cell cycle?

Back

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

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two sister chromatids for each chromosome.

Front

What is the G2 phase?

Back

The G2 phase is the period after DNA replication where the cell prepares for mitosis, including further growth and organelle duplication.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

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, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is metaphase?

Back

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

Front

What happens during anaphase?

Back

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

Front

What occurs during telophase?

Back

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