MOLECULAR BIOLOGY: Ambiguous Dogma

Tracking the Resolution of Student Misconceptions about the Central Dogma of Molecular Biology†

The goal of our study was to track changes in student understanding of the central dogma of molecular biology before and after taking a genetics course. Concept maps require the ability to synthesize new information into existing knowledge frameworks, and so the hypothesis guiding this study was that student performance on concept maps reveals specific central dogma misconceptions gained, lost,...

Macro-trends in research on the central dogma of molecular biology

The central dogma of molecular biology, formulated more than five decades ago, compartmentalized information exchange in the cell into the DNA, RNA and protein domains. This formalization has served as an implicit thematic distinguisher for cell biological research ever since. However, a clear account of the distribution of research across this formalization over time does not exist. Abstracts ...

A world in one dimension: Linus Pauling, Francis Crick and the central dogma of molecular biology.

In 1957, Francis Crick outlined a startling vision of life in which the great diversity of forms and shapes of macromolecules was encoded in the one-dimensional sequence of nucleic acids. This paper situates Crick's new vision in the debates of the 1950s about protein synthesis and gene action. After exploring the reception of Crick's ideas, it shows how they differed radically from a different...

A scientific revolution? The prion anomaly may challenge the central dogma of molecular biology.

Science, Thomas Kuhn argued in The Structure of Scientific Revolutions (1962), proceeds at two different paces. One is what he called “normal science”, which professionals, the general public, the press and politicians generally understand as “research firmly based upon one or more past achievements that some particular scientific community acknowledges for a time as supplying the foundation fo...
