Answer» CORRECT option is (a) For microarray data, CLUSTERING analysis identifies coexpressed and coregulated genes To elaborate: When genes are co-regulated, they normally reflect RELATED functionality. Through GENE clustering, functions of previously uncharacterized genes may be discovered. Clustering methods include hierarchical clustering and partitioning clustering (e.g., k-means, self-organizing MAPS [SOMs]).
