Mi and Microarray

In this image of a microarray the red dots indicate

• genes that are upregulated in cancer tissue

• genes that are down regulated in healthy tissue

• genes that are not expressed in cancer tissue

• genes that are equally expressed in both cancer and healthy tissue

Using microarray technology researchers found that the tumor suppressor gene BRCA2 were ________ in cancer tissue.

• Upregulated

• Down Regulated

• Unregulated

• Equally expressed
