Cell Cycle

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 replication. It consists of interphase (G1, S, G2 phases) and the mitotic phase (M phase).

Front

What happens during interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division. It includes G1 (cell growth), S (DNA 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 includes several phases: prophase, metaphase, anaphase, and telophase.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes align in the middle of the cell, preparing to be separated into daughter cells.

Front

What is cytokinesis?

Back

Cytokinesis is the final step of cell division, where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is the purpose of cell division?

Back

Cell division is necessary for growth, replacement of dying cells, and repair of damaged tissues.

Front

What is the S phase?

Back

The S phase (synthesis phase) is part of interphase where DNA is replicated, resulting in two copies of each chromosome.

Front

What happens 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 the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms in the cell cycle that ensure the proper progression of the cycle, preventing errors such as DNA damage or incomplete replication.

Front

What is the G1 phase?

Back

The G1 phase (gap 1 phase) is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.
