 Ribonomics, like genomics or proteomics, is the large-scale, high-throughput approach to identifying subsets of RNAs by their association with proteins in cells.Since many messenger RNAs (mRNAs) are linked with multiple processes, this technique offers a facile mechanism to study the relationship of various intracellular systems.Prokaryotes co-regulate genes common to cellular processes via a polycistronic operon.
