DNA is directly photographed for the first time

This article discusses the recent photographs taken of DNA.  In the past, from when DNA was first discovered until now, the structure of it was only known through other methods like observing how X-Rays bounces off of it when they collide with it.  The journalist opens the article by iterating that it has taken 59 years since DNA's initial discovery to confirm what is actually looks like.  The journalist then uses logos to explain the process of the Italian physics professor, Enzo Di Fabrizio, to finally confirm scientists' hypothesis about the appearance of DNA.  The journalist then includes Di Fabrizio's opinion that advances in technology will soon produce clearer pictures of the DNA strands.  The article concludes with a statement about how these photographs will greatly help scientists with their future work in genetics.  Through the inclusion of the facts of the photographs and how it will affect science, the journalist effectively uses logos to convey to the readers how monumental this discovery is.
