TRANSCRIPT ANALYSIS. “To understand the role that gene duplication and gene expression diversity may play in controlling metabolic pathways, I analyzed transcript accumulation for the complete genome. This analysis includes 21,460 genes for which there are both microarray data and assigned duplication status. 12,676 genes are classified as unique.”
