For a particular microarray assay (DNA chip), cDNA has been made from the mRNAs of a dozen patients' breast tumor biopsies. Which of the following types of evidence will researchers be looking for in order to determine if the cells are cancerous?
A) a particular gene that is amplified in all or most of the patient samples
B) a pattern of fluorescence that indicates which cells are over proliferating
C) a pattern shared among some or all of the samples that indicates gene expression differing from control samples
D) a group of cDNAs that match those in non-breast cancer control samples from the same population

Researchers will be looking for a pattern shared among some or all of the breast tumor biopsy samples that indicates gene expression differing from control samples. This pattern of differential gene expression can be used as evidence to determine if the cells are cancerous or not.
