Distribution of highly conserved sequence across ncRNA exon sequences. Examples of phastCons elements (as in ) within (a) lincRNA (located on chromosome 10, 68730506-68731547) and (b) macroRNA (located on chromosome 1, 47378880-47380310) exons. Blue histograms represent the conservation in 17 vertebrates based on a phylogenetic hidden Markov model . Green histograms represent pairwise conservation to other vertebrate species. Images have been taken from the UCSC genome browser.
