Review Cell Cycle, Mitosis & Cancer

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, including G1, S, G2, and M phases.

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

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

Front

What is the purpose of mitosis?

Back

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

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

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 the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle and prevent errors.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division due to mutations in genes that regulate the cell cycle.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous and do not spread, while malignant tumors are cancerous and can invade nearby tissues.

Front

What is apoptosis?

Back

Apoptosis is programmed cell death that helps eliminate damaged or unnecessary cells.
