The editor's intro note to an article on molecule biology in The Economist (Really New Advances, June 14, 2007) reads:
"Molecular biology is undergoing its biggest shake-up in 50 years, as a hitherto little-regarded chemical called RNA acquires an unsuspected significance."
Unsuspected significance?
Unsuspected means "not suspected, not believed to be likely." That is to say, the importance of RNA, which, the article explains, "looked a bit like DNA but wasn't" may have been overlooked. In fact, its "significance" has been overlooked, which is the whole point of the article.
According to the article, DNA, "in the form of genes, contained the instructions for making proteins" whereas RNA "obediently carried genetic information from DNA in the nucleus to the places in the cell where proteins are made.
"All that was worked out decades ago. Since then, RNA has been more or less neglected as a humble carrier of messages and fetcher of building materials. This account of the cell was so satisfying to biologists that few bothered to look beyond it. But they are looking now. For, suddenly, cells seem to be full of RNA doing who-knows-what" (if you want to read the story in full, hit thislinkhttp://www.economist.com/science/displaystory.cfm?story_id=9333471&CFID=7934141&CFTOKEN=38686699).
Anyways, RNA's significance has been overlooked because it was previously unsuspected - not suspected to exist.
