James Watson and Francis Crick worked out the structure of the DNA double-helix at Cambridge University, announcing their much-celebrated discovery in a modest one-page letter to the journal Nature that was published 50 years ago today...
It’s the network, not the double helix, that is attracting the attention of more and more scientists. Fifty years after the structure of DNA invigorated the molecular biology revolution, a new more integrated approach to understand cells is gaining prominence...
...task for scientists is to study how these bases of DNA are grouped into genes, and how these genes help produce proteins that interact to keep a cell alive...
Laura Garwin ’77, director of research affairs for the Bauer Center, says the more comprehensive approach to understanding how DNA directs the functions of the cell should not overshadow the importance of the reductionist approach used so successfully by Watson and Crick, and thousands of others...
...crucial piece of technology for understanding biological networks is the DNA microarray, invented in the early 1990s. The microarray allows scientists to determine, all at once, the relative levels at which genes are expressed in cells...
