Scientists carried out a microarray analysis to compare the gene expression of normal pancreatic cells to that of cancer cells from a person with pancreatic cancer. The scientists labeled the cDNA from the normal pancreatic cells with green fluorescent nucleotides. They labeled the cDNA from the cancer cells with red fluorescent nucleotides.  The two cDNAs were mixed and allowed to hybridize to a microarray. Less p53 activity is found in cancer pancreatic cells than normal cells.  What color would the spot for the p53 gene be on the microarray?  Red Green Yellow Black
