Cell cycle

What is a fundamental principle of Modern Cell Theory regarding living organisms?

• All living things are made of cells.

• Cells are the largest unit of life.

• Cells can spontaneously generate.

• Only multicellular organisms 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.

• Cells fuse together to form larger cells.

Which of the following is a characteristic of cancer cells?

• They always communicate effectively with healthy cells.

• They divide too frequently and are unregulated.

• They securely anchor themselves to their original location.

• They are unable to secrete their own growth hormone.

What is the phase of the cell cycle where cells spend most of their time growing, replicating DNA, and performing normal functions, rather than dividing?

• Mitosis

• Cytokinesis

• M phase

• Interphase

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

• G1, S, and M

• G1, G2, and M

• S, G2, and M

• G1, S, and G2

What critical event occurs during the S phase of the cell cycle?

• Cell growth

• DNA replication

• Preparation for mitosis

• Cell division

What does the metaphase checkpoint primarily ensure during cell division?

• The cell has enough resources to divide.

• The DNA is not damaged.

• Chromosomes are correctly aligned and attached to the spindle.

• The cell has grown sufficiently.

What is the process called when a cell self-destructs because it is damaged beyond repair?

• Mitosis

• Apoptosis

• Cell Limbo

• Synthesis
