WildUtah is referring to chemical modifications (methylation, associated with epigenetics: http://www.whatisepigenetics.com/dna-methylation/ http://www.whatisepigenetics.com/dna-methylation/), the structure of [eukaryotic] genes (intron/exon, start and stop; things many elementary students know of -- and subsequently forget) and palindromic elements. Palindromic elements are most closely related to what the linked paper is about. Basically, instead of existing as a normal double helix, the two strands separate and bind with the palindrome on the same strand; like making an X with DNA: https://en.wikipedia.org/wiki/Palindromic_sequence https://en.wikipedia.org/wiki/Palindromic_sequence . Ultimately, this is a crappy press release for a paper that, as _of points out, is scientifically correct but otherwise dull. The paper is going back to first principles, as it were, for DNA and looking at factors in DNA alone that contribute to its function (well, 'normal', non-methylated, potentially histone associated DNA).
