> Also this research has emphasized the 3-D nature of DNA. Tightly coiled around histones the double helix presents genes to midifier sections in close proximity, while if the model of DNA is presented strung out in straight lines the modifying triggers seem far apart. My thought is that some junk is conserved simply as buffer material to allow for proper 3-D spacing. DNA looks to be brilliantly conceived, much to atheist dismay.-"Feng comments:

The quote from Sydney above that "the "junk" DNA might be required to maintain the viscosity of the nucleus" is really interesting. In a similar vein, we have done some studies, which show that some DNA sequences in the genome may just be "filler" sequences to keep adjacent functional ones from doing too much."-Sean Eddy comments:

Feng: I agree, and I think that's part of the slipperiness of the term "function", and why the term "junk" is only a colloquialism. The junk on my desk is junk, but if you suddenly removed it, my coffee cup would fall over and spill into my laptop; the junk has become part of the system.-These comments are from a very decisive discussion by knowledgeable researchers on a very interesting blog:-http://selab.janelia.org/people/eddys/blog/?p=683-And more secearch on gene regulation:-http://medicalxpress.com/news/2012-09-uncovering-genome-regulatory-code.html
