Cell Cycle and Cancer Characteristics

What is a fundamental principle of the Modern Cell Theory?

• All living things are made of cells.

• Cells can spontaneously generate.

• Cells are the largest unit of life.

• Only animals are made of cells.

How do multicellular organisms primarily grow in size?

• Individual cells increase significantly in size.

• Cells absorb more water to expand.

• By making more cells through cell division.

• Through the fusion of existing cells.

Which of the following is a characteristic of cancer cells?

• They communicate effectively with healthy cells.

• They divide in an uncontrolled manner.

• They securely anchor themselves to surrounding tissues.

• They require fewer nutrients than healthy cells.

Which phase of the cell cycle involves cell growth, DNA replication, and performing normal cell functions, rather than cell division?

• Mitosis

• Cytokinesis

• Interphase

• M phase

Which of the following phases are collectively known as Interphase in the cell cycle?

• G1, S, and G2

• G1, S, and M

• G2, M, and S

• G0, G1, and S

What is the primary event that occurs during the S phase of the cell cycle?

• Cell growth and preparation for mitosis

• Replication of DNA

• Division of the cell

• Checking for DNA damage and resources

Which of the following is NOT a factor checked at the G1 checkpoint of the cell cycle?

• Adequate cell growth

• Presence of DNA damage

• Sufficient resources for progression

• Correct alignment of chromosomes

What is the outcome for a cell that fails a cell cycle checkpoint and cannot repair the detected issue?

• It enters a permanent resting phase (G0)

• It proceeds to the next phase with errors

• It undergoes programmed cell death

• It becomes a specialized cell type

What characterizes cells in the G0 phase of the cell cycle?

• They are actively dividing and replicating DNA

• They are preparing for mitosis but not growing

• They perform normal functions but do not prepare to divide

• They are undergoing apoptosis due to irreparable damage
