What is the G0 phase?

• The G0 phase is a resting state in the cell cycle.

• The G0 phase is when cells undergo apoptosis.
• The G0 phase is a stage of mitosis.
• The G0 phase is when DNA is replicated.

Under what circumstances will a cell enter the G0 phase?

• A cell enters the G0 phase during apoptosis.

• A cell enters the G0 phase when it is not actively dividing.

• A cell enters the G0 phase when it is preparing for mitosis.
• A cell enters the G0 phase when it is actively synthesizing DNA.

What is the first checkpoint of the cell cycle?

Why is the G1 checkpoint the most important checkpoint in mitosis?

• The G1 checkpoint is the most important because it is when the cell's DNA doubles, and DNA is replicated.

• The G1 checkpoint is the most important because, if passed, proteins will signal the cell to begin mitosis.

• The G1 checkpoint is the most important because it ensures the cell is ready for DNA replication and checks for any damage before proceeding.

What is the second checkpoint in mitosis?

Why is the Synthesis phase important?

• It is the final phase of a project.
• It is primarily about evaluating past performance.
• It focuses solely on data collection.
• It is important for integrating insights and fostering innovative solutions.
