Watson and Crick

       The article proposes the double helix structure for DNA. This article was published in 1953 by Watson and Crick in Nature, a scientific journal. Watson and Crick published their paper early, without large amounts of detail, because they wanted to first to discover the structure of DNA. This worked and they won a Nobel Prize for their work. They wrote to the scientific community in order to propose their structure for DNA and mention that their structure suggests how DNA replicates.
The article focuses on logos, and is fairly devoid of pathos. First Watson and Crick dismissed the previous models of DNA as ill defined or not completely following the laws of chemistry. When they discuss their model they insure it does not have such problems and reference experimental data and rules of chemistry that helped them come to their conclusion. They do not have many strong appeals to ethos, but they do mention the work of many other people who helped them come to their conclusions. This appeals the their credibility because it shows how their work was based upon other scientists.
