• The process of cells becoming identical

• The process of cells becoming mutated

What is gene regulation?

• DNA Replication

• The formation of new genes within the DNA

• Uncontrolled cell growth with damaged DNA

• The expression of genes to in order to create cell types

Specialized cells such as muscle, blood, or nerve cells are caused by cell differentiation led by

• Environmental Factors

• nucleus

• ribosomes

• plasma membrane

Cells differentiate to perform different functions because

• all genes are turned on inside that cell

• all genes are turned off inside that cell

• different genes are turned on inside that cell

• different genes are turned on or off inside that cell

During the process of differentiation

• all sections of DNA are activated to determine the structure of a body cell

• ONLY ONE section of DNA are deactivated to determine the structure of a body cell

• only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

• differentiated cells

• nerve cells

• stem cells

• Cancer Cells

• Zygotes

• Specialized Cells

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.
