Mitosis

What is the phase called when the cells actually divide, including the division of the nucleus and cytoplasm?

• G1 phase

• S phase

• M phase

• G2 phase

What is the process called when the nucleus divides?

• Cytokinesis

• Mitosis

• Interphase

• S phase

What is the process called when the cytoplasm divides?

• Mitosis

• Interphase

• Cytokinesis

• G1 phase

When does the cell cycle begin and end?

• Begins when a parent cell divides and ends when the organism dies

• Begins when two new cells are formed by division of a parent cell and ends when one of these cells divides again

• Begins at birth and ends at death

• Begins when DNA synthesis starts and ends when DNA synthesis stops

What is the G1 phase also known as?

• Gap 1 phase

• S phase

• G2 phase

• M phase

What is a major decision made during the G1 phase?

• Whether a cell will divide again

• Whether DNA synthesis will occur

• Whether the cell will undergo mitosis

• Whether the cell will enter the G2 phase

What are cells that arrest in G1, waiting for a signal to divide, said to be in?

• G0 (G zero)

• S phase

• G2 phase

• M phase

What is the term used for cells that exit the cell cycle?

• Terminal differentiation

• Apoptosis

• Mitosis

• Cytokinesis

What happens to the DNA during the S phase of the cell cycle?

• DNA is degraded

• DNA is replicated

• DNA is transcribed

• DNA is translated

What is the ploidy level of the cell after DNA replication in the S phase?

• 2n

• 3n

• 4n

• 1n
