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 the mitotic phase (Mitosis and Cytokinesis).

Front

What occurs during Gap 1 (G1) phase of the cell cycle?

Back

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

Front

What happens during the Synthesis (S) phase of the cell cycle?

Back

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

Front

What is Gap 2 (G2) phase?

Back

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 is a tumor?

Back

A tumor is a mass of rapidly growing abnormal cells that can be benign (non-cancerous) or malignant (cancerous).

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 happens during Metaphase?

Back

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

Front

What is Anaphase?

Back

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