Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation until it divides into two daughter cells. It includes interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

Front

What occurs during Interphase?

Back

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

Front

What is Mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two genetically identical daughter cells.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is Metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up at the cell's equatorial plane, preparing for separation.

Front

What occurs during Anaphase?

Back

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

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

What are Cyclins?

Back

Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases (CDKs), which drive the cell through different phases.
