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 duplication (replication). It consists of interphase (G1, S, G2) and mitotic phase (M).

Front

What happens during G1 phase of Interphase?

Back

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

Front

What occurs during the S phase of Interphase?

Back

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

Front

What is the G2 phase of Interphase?

Back

The G2 phase is the final stage of interphase where the cell continues to grow, makes new organelles, and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the stages of mitosis?

Back

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

Front

What happens during prophase?

Back

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

Front

What occurs during metaphase?

Back

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

Front

What is anaphase?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the cell begins to divide.
