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 the mitotic phase (M).

Front

What happens during the G1 phase of the Cell Cycle?

Back

During the G1 phase, the cell grows and prepares 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 M phase in the Cell Cycle?

Back

The M phase is the mitotic phase where the cell divides into two daughter cells.

Front

What is a benign tumor?

Back

A benign tumor is a non-cancerous growth that does not spread to other parts of the body.

Front

What is a malignant tumor?

Back

A malignant tumor is cancerous and can invade nearby tissues and spread to other parts of the body (metastasis).

Front

What is the purpose of checkpoints in the Cell Cycle?

Back

Checkpoints are mechanisms that ensure the cell is ready to proceed to the next phase, preventing errors.

Front

What happens during Prophase I of meiosis?

Back

During Prophase I, homologous chromosomes pair up and exchange genetic material through crossing over.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells after mitosis or meiosis.
