Cell Cycle and Mitosis

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 happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions, preparing for DNA replication.

Front

What is the S phase in the cell cycle?

Back

The S phase is the part of the cell cycle where DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What occurs during the G2 phase?

Back

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

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the main stages of mitosis?

Back

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

Front

What is the purpose of cytokinesis?

Back

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

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division by growing and replicating its DNA.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms in the cell cycle that ensure the proper division of the cell and prevent errors.

Front

What is the difference between a benign and malignant tumor?

Back

A benign tumor is non-cancerous and does not spread, while a malignant tumor is cancerous and can invade nearby tissues and spread to other parts of the body.
