The Cell Cycle Review

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. It consists of phases: interphase, mitosis, and cytokinesis.

What happens during Interphase?

Back

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

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells. It consists of several stages: prophase, metaphase, anaphase, and telophase.

Front

What occurs in Prophase?

Back

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

Front

What is Metaphase?

Back

Metaphase is the second stage of mitosis where chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What happens during Anaphase?

Back

During Anaphase, the sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the 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 process that follows mitosis, where the cytoplasm of the cell 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 before cell division, ensuring that each daughter cell receives a complete set of genetic information.

Front

What is the significance of the Cell Cycle?

Back

The Cell Cycle is crucial for growth, development, and repair in multicellular organisms, allowing for the replacement of damaged or dead cells.
