In one type of microarray, hybridization of red (experimental) and green (control) labeled cDNAs is proportional to the relative amounts of mRNA in the samples. Red indicates the overexpression of a gene and green indicates the underexpression of a gene in the experimental cells relative to the control cells, yellow indicates equal expression in experimental and control cells, and no color indicates no expression in either experimental or control cells.arrow_forwardMicroarrays can be used to determine relative levels of gene expression.
