What is the role of mitosis in multicellular organisms?

• It allows multicellular organisms to grow by making more cells.

• It increases the size of each cell.

• It decreases the number of cells.

• It replaces cells with bacteria.

Why is uncontrolled cell division a problem?

• It leads to the organism shrinking.

• It can result in cancer.

• It makes cells lose their specialization.

• It stops the production of new cells.

What phase do cells spend most of their time in?

• M phase

• Telophase

• Interphase

• Prophase

What is the purpose of checkpoints in the cell cycle?

• To stop cells from performing their specialized functions.

• To check that the cell is ready to divide.

• To initiate the cell's self-destruction regardless of its condition.

• To ensure cells divide as frequently as possible.

What happens if a cell cannot pass a checkpoint?

• It immediately divides.

• It exits the cell cycle permanently.

• It pauses until the issue is fixed or undergoes apoptosis if it can't be fixed.

• It transforms into a different type of cell.

What are cyclin and Cdk?

• Proteins involved in positive regulation of the cell cycle.

• Types of cancer cells.

• Negative regulators of the cell cycle.

• Types of checkpoints in the cell cycle.

What is apoptosis?

• A type of cell division.

• The process of DNA replication.

• The cell's self-destruction mechanism.

• A phase in the cell cycle.

What is G0 phase?

• A phase where cells divide uncontrollably.

• A phase where cells prepare to exit the cell cycle.

• A resting phase where cells are not preparing to divide.

• The phase where DNA replication occurs.
