A virus is a small, infectious agent that is made up of a core of genetic material surrounded by a shell of protein. The genetic material (which is responsible for carrying forward hereditary traits from parent cells to offspring) may be either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Viruses are at the borderline between living and nonliving matter. When they infect a host cell, they are able to carry on many life functions, such as metabolism and reproduction.

For Ms. Cantu, the GRB7 gene is not expressed in malignant breast tissue while the ESR1 gene is upregulated in such tissue.
Upregulated genes are shown by the colour red.
Down-regulated genes are shown by the colour green.
Non-differentially expressed genes are indicated by the colour yellow.
Absence of expression is shown by the colour black.
Hence from the table and colours ESR1 The GRB7 gene is not expressed, and the gene is upregulated.
