How do the white sectors arise in the second colony of yeast cells when the yeast Ade2 genes are not expressed. Introduction: The yeast Ade2 encodes one of the enzymes that required for the adenine biosynthesis. The gene expression is repressed when adenine is present while it is slightly increased under conditions of the amino acid starvation. When the gene is expressed, the yeast colony will be in white and when the gene is not expressed, the colony will have a red pigmentation.
