Cell Cycle and Cancer CFA #1

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is a checkpoint in the cell cycle?

Back

A checkpoint is a regulatory point in the cell cycle where the cell assesses whether to proceed with division, ensuring that damaged or mutated cells do not divide.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell growth and division, often due to mutations that bypass cell cycle checkpoints.

Front

What are somatic cells?

Back

Somatic cells are non-reproductive cells that make up most of the body's tissues and organs, and they are genetically identical to each other.

Front

What are gametic cells?

Back

Gametic cells are reproductive cells (sperm and eggs) that are genetically different from each other due to meiosis.

Front

What role do growth factors play in the cell cycle?

Back

Growth factors are proteins that stimulate cell division and growth, acting as signals for cells to progress through the cell cycle.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows, performs normal functions, and prepares for DNA replication.

Front

What occurs during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis, ensuring all DNA is replicated and undamaged.

Front

What is cytokinesis?

Back

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