STUDY GUIDE: 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 duplication (replication). It consists of phases: G1, S, G2, and M.

Front

What occurs during the S phase of the Cell Cycle?

Back

During the S phase (Synthesis phase), DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What happens during Anaphase of Mitosis?

Back

During Anaphase, the sister chromatids are pulled apart toward opposite poles of the cell.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the nuclear envelope re-forms around each set of chromosomes, which begin to decondense.

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 is Cancer in relation to the Cell Cycle?

Back

Cancer is the uncontrolled growth and division of cells, often due to mutations that disrupt normal cell cycle regulation.

Front

What is the role of the G1 phase in the Cell Cycle?

Back

The G1 phase (Gap 1) is the first phase of interphase where the cell grows and prepares for DNA replication.

Front

What occurs during the G2 phase of the Cell Cycle?

Back

During the G2 phase (Gap 2), the cell continues to grow and prepares for mitosis, ensuring all DNA is replicated and undamaged.

Front

What is the significance of checkpoints in the Cell Cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle, preventing errors such as DNA damage.
