• 40

• 240

• 10

Why do hormones not affect every cell in the body when they are released?

• All cells are affected by a hormone when it is released

• A cell needs a specific receptor for the hormone to be affected

• A cell must have the proper ATP levels to activate a cellular response

• Cells need compatible DNA for the hormone to activate transcription of a gene

In which phase of mitosis do the sister chromatids line up on the equator of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

During which stage of interphase does the DNA duplicate.

• M Phase

• G1 Phase

• S Phase

• G2 Phase

In the G1 stage of the cell cycle, the cell

• Grows

• Matures

• Carries on normal activities

• All of the above

How does the concentration of cyclin change as a cell goes through the cell cycle?

• Cyclin concentration remains constant.

• Cyclin concentration increases during interphase and decreases during mitosis.

• Cyclin concentration decreases during interphase and increases during mitosis.

• Cyclin concentration is inversely related to MPF concentrations.

How does the concentration of cyclin dependent kinases (Cdk) change as the cell proceeds through the cell cycle?

• Cdk concentration remains constant.

• Cdk concentration increases during interphase and decreases during mitosis.

• Cdk concentration decreases during interphase and increases during mitosis.

• Cdk concentration correlates directly with MPF concentration.

The point of attachment between two sister chromatids is called

• kinetochore

• centromere

• chromosome

• spindle

This is the cell cycle checkpoint that makes sure the correct number of chromosomes are present and attached to microtubules.

• G1 Checkpoint

• G2 Checkpoint

• M Checkpoint

• I Checkpoint
