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 phases including interphase, mitosis, and cytokinesis.

What are the main phases of the Cell Cycle?

Back

The main phases of the Cell Cycle are Interphase (G1, S, G2), Mitosis (Prophase, Metaphase, Anaphase, Telophase), and Cytokinesis.

What happens during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis. It consists of three sub-phases: G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

What is Mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two identical daughter cells. It includes four stages: prophase, metaphase, anaphase, and telophase.

What occurs during Prophase?

Back

During Prophase, the 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 line up in the middle of the cell, and spindle fibers attach to the centromeres of the chromosomes.

Front

What occurs during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite ends of the cell by the spindle fibers.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes reach the opposite poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is Cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is DNA Replication?

Back

DNA Replication is the process by which a cell makes an exact copy of its DNA, ensuring that each daughter cell receives a complete set of genetic information.
