• ENCODE threads Explorer Characterization of intergenic regions and gene definition. (wikipedia.org)
  • Additionally gene trees, generated by comparative analysis of DNA segments, do not always fit the species tree. (wikipedia.org)
  • The first exon of a 'trapped' gene splices into the exon that is contained in the insertional DNA. (wikipedia.org)
  • Other studies on plants have discovered crucial functions in portions of noncoding DNA that were previously thought to be negligible and have added a new layer to the understanding of gene regulation. (wikipedia.org)
  • Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions, and is being explored in evolutionary developmental biology. (wikipedia.org)
  • These single-locus sources of DNA do not recombine and are almost always inherited from a single parent, with only one known exception in mtDNA. (wikipedia.org)
  • The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity. (wikipedia.org)
  • When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. (wikipedia.org)
