Cancer, Differentiation, and Stem Cells

Stem cells can be obtained from

• embryos
• some adult tissues
• umbilical cord blood
• all of the above

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering
• survival of the fittest
• differentiation
• selective breeding

Which best explains why muscle cells are different from blood cells?

• Muscle cells are produced by the brain, but blood cells are produced by the heart. 
• Different genes are activated in muscle cells than in blood cells. 
• Muscles cells experience different environmental influences than blood cells. 
• A mutation occurs during the development of muscle cells but not in blood cells. 

Which type of cell is unspecialized?

• skin cell
• stem cell
• liver cell
• muscle cell

During which phase of the cell cycle does cell division occur?

• G1 Phase
• M Phase
• S Phase
• G2 Phase

What is the importance of the S Phase?

• The cell grows larger. 
• Organelles are duplicated.
• DNA is replicated.
• The cell divides into two daughter cells. 

During what phase of Mitosis do the chromosomes line up in the Middle

• Metaphase

• Prophase

• Telophase

• Anaphase

Which of the following is the correct order of the Cell Cycle?

• Interphase, Mitosis, Cytokinesis

• Mitosis, Cytokinesis, Mitosis, Interphase

• Prophase, Metaphase, Anaphase, Telophase

• Interphase, Prohase, Cytokinesis

In which phase of Mitosis do the Chromosomes pull Apart

• Metaphase

• Prophase

• Anaphase

• Telophase

In which phase does a cell spend most of its life?

• Interphase

• Prophase

• Metaphase

• Anaphase

• Telophase
