The Cell Cycle

Front

What is the G0 phase in the cell cycle?

Back

The G0 phase is a resting or quiescent stage where the cell is not actively preparing to divide and may exit the cell cycle temporarily.

Front

What is interphase and its significance in the cell cycle?

Back

Interphase is the longest stage of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis. It consists of G1, S, and G2 phases.

Front

What occurs during the S phase of interphase?

Back

During the S phase, DNA replication occurs, resulting in the duplication of the cell's genetic material.

Front

What is mitosis and its role in the cell cycle?

Back

Mitosis is the process of nuclear division that results in two identical daughter cells, ensuring equal distribution of genetic material.

Front

What are the main stages of mitosis?

Back

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

Front

What happens during the G1 phase of interphase?

Back

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

Front

What is the purpose of the G2 phase in the cell cycle?

Back

The G2 phase is the final preparation stage for mitosis, where the cell checks for DNA damage and ensures all DNA is replicated.

Front

Which phase of the cell cycle is characterized by the cell preparing for division?

Back

The G2 phase is characterized by the cell preparing for division.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the cell cycle progresses only when certain conditions are met, preventing errors in cell division.

Front

What is the difference between the M phase and interphase?

Back

The M phase includes mitosis and cytokinesis, while interphase consists of G1, S, and G2 phases where the cell prepares for division.
