Comments P.1311 left column bottom paragraph: "A distinguishing feature of metazoan genomes is the abundance of noncoding RNA (ncRNAs), which function by means other than directing the production of proteins. In addition to small regulatory RNAs such as miRNAs, recent studies have predicted the existence of long ncRNAs—ranging from 300 nucleotides (nt) to over 10 kb—that are spliced, polyadenylated, and roughly as diverse in a given cell type as protein-coding mRNAs (primary sources). Long ncRNAs may have diverse roles in gene regulation, especially in epigenetic control of chromatin (Bernstein and Allis, 2005)."
