It is amazing!!</div><div>I would like to highlight the word "constraints" at the caption of the DNA diagram (<a href="http://phys.org/news/2016-06-layer-dna.html">http://phys.org/news/2016-06-layer-dna.html</a>)</div><div>"The rigid base-pair model is forced, using 28 <b>constraints </b>(indicated by red spheres), into a lefthanded superhelical path that mimics the DNA conformation in the nucleosome.

Of course, to work current (complex, innovative) science you must have an interdisciplinary approach.</div><div><br></div><div>Abraço.</div><div><br></div><div>Moisés</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">2016-06-08 16:40 GMT-03:00 John Collier <span dir="ltr"><<a href="mailto:Collierj@ukzn.ac.za" target="_blank">Collierj@ukzn.ac.za</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
