Apologies for a trivial objection: but the serpentine icon associated with this, likely otherwise fine, package embodies an odd little annoyance to all us structural biochemists:  It depicts the DNA helix as left-handed.  This is a rare form of DNA at best, most likely an unlucky graphical choice, and causes many nerdy folk to suspect that you don&#x27;t know what you&#x27;re doing. If you think i&#x27;m nuts (and hey maybe...) there are entire websites devoted to this error, because for some reason it&#x27;s a common error and makes our eyes bleed [wink]: <a href="http:&#x2F;&#x2F;users.fred.net&#x2F;tds&#x2F;leftdna&#x2F;" rel="nofollow">http:&#x2F;&#x2F;users.fred.net&#x2F;tds&#x2F;leftdna&#x2F;</a>
