What does the RED color indicate in DNA microarray?

• these genes are not expressed in healthy cells

• there are no genes in these cells

• these genes are expressed in cancer

• these genes are not expressed in cancer

What does the BLUE color indicate in DNA microarray?

• these genes are expressed in cancer

• these genes are expressed in healthy cells

• these genes are not expressed in healthy cells

• there are no genes in these cells

What does the PURPLE color indicate in DNA microarray?

• this gene is expressed in cancer cells only

• this gene is expressed in healthy cells

• there are no genes in the cell

• this gene is expressed in both cancer and healthy cells

Gene regulation is the process of doing what?

• producing proteins

• replicating DNA

• producing RNA

• determining which genes will be turned on or off

True or False: One example of gene regulation is when the cells from the breast do not produce insulin the way that the cells from the pancreas do.
