Four different types of cells are shown. Which characteristic is shared by all four cells?

• A mechanism for transforming sunlight into energy

• Self-locomotion

• Membrane-bound organelles that transport substances

• Genetic material composed of DNA

Checkpoints occur between the stages of the cell cycle. If a cell does not meet certain criteria at the end of a stage, it will not move to the next stage. Which of these occurs just before the cell enters the G stage of the cell cycle?

• The nuclear membrane disintegrates.

• DNA replicates.

• Centrioles form.

• The nucleolus divides.

The diagram shows cells in different phases of mitosis. A student is trying to find a cell in a

particular phase of mitosis. The student is looking for evidence that spindle fibers are

separating the chromosomes to ensure that each new nucleus has one copy of each

chromosome. Which cell is in the phase of mitosis that the student is searching for?

• Cell 1

• Cell 2

• Cell 3

• Cell 4

Cells pass through a G checkpoint before entering mitosis. Ideally, if DNA damage is 2

detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage

repaired before cells enter mitosis?

• So that another round of DNA synthesis does not have to take place.

• So that the chromosomes can align at the metaphase plate during mitosis.

• So that the cytoplasm can be divided equally between the two daughter cells.

• So that healthy daughter cells are produced, allowing the organism to continue growing.

Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow and divide, or by dying. In 2010 a group of scientists reported that a certain kind of immune reaction can cause DNA damage that leads to a fourth response. DNA damage can turn off genes involved in cell-signaling pathways. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of —

• tumors

• allergies

• hemophilia

• cardiovascular disease

Checkpoints occur between the stages of the cell cycle. If a cell does not meet certain criteria at the end of a stage, it will not move to the next stage. Which of these occurs just before the cell enters G2 stage of the cell cycle?

• The nuclear membrane disintegrates

• DNA replicates

• Centrioles form

• The nucleolus divides
