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 to its division into two daughter cells. It includes interphase and the mitotic phase.

Front

What are the three main phases of interphase?

Back

The three main phases of interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

What happens during the S phase of interphase?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is mitosis?

Back

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

Front

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 happens during metaphase?

Back

During metaphase, chromosomes line up 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.

Front

What occurs during telophase?

Back

During telophase, 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 divides, resulting in two separate daughter cells.

Front

What is the G0 phase?

Back

The G0 phase is a resting state where cells are not actively preparing to divide and may remain in this phase for extended periods.
