The Watson and Crick Structure of DNA

Today, our series on models of DNA is concluded with a discussion of the correct structure determined by James Watson and Francis Crick. Although they made an unlikely pair, the two men succeeded where one of the era’s leading scientists – Linus Pauling – failed, and in the process they unraveled the secrets of what [...]

The Pauling-Corey Structure of DNA

Today, the structure of DNA series is continued with the model proposed by Linus Pauling and Robert Corey in 1953. As a result of insufficient data and an overloaded research schedule, Pauling’s structure turned out to be incorrect. However, it is interesting to see the ways in which one of the world’s leading scientists went [...]

The Fraser Structure of DNA

Today, the DNA series is continued with a post discussing a mostly correct structure that almost emerged from King’s College in the early 1950s. Although Maurice Wilkins, Rosalind Franklin, and Bruce Fraser each contributed information for the structure, it was Fraser that actually put the pieces together and built a model. Therefore, today’s post will [...]

The Race for DNA: The Ronwin Structure

This post marks the beginning of an extensive series of posts on DNA. The first four posts in the series will cover structures of DNA proposed by various individuals, including one by Linus Pauling, as well as the correct structure discovered by James Watson and Francis Crick. Today, an early structure proposed by Edward Ronwin [...]
