1953: When Genes Became “Information”
نویسنده
چکیده
In 1953, Watson and Crick not only described the double-helix structure of DNA, but also embraced the idea that genes contained a code that expresses information and thereby changed our view of life. This article traces how these ideas entered biological thinking and highlights the connections between different branches of science at the time, exploring the power of metaphor in science.

Comparative Genome Analysis of Rathayibacter tritici NCPPB 1953 with Rathayibacter toxicus Strains Can Facilitate Studies on Mechanisms of Nematode Association and Host Infection
Rathayibacter tritici, which is a Gram positive, plant pathogenic, non-motile, and rod-shaped bacterium, causes spike blight in wheat and barley. For successful pathogenesis, R. tritici is associated with Anguina tritici, a nematode, which produces seed galls (ear cockles) in certain plant varieties and facilitates spread of infection.

متن کاملThe Detection of Linkage in Tetrad Analysis.
STABLISHING the existence of linkage between genes at two loci is a E distinct problem from estimating map-distance once genes are known to be linked. This paper considers two questions that concern linkage detection in organisms with genetically analyzable tetrads. First, what criterion is best for establishing linkage when tetrad segregations are analyzedl? And second, what are the advantages...

Although there is extensive information con cerning regression of the Rous sarcoma, the sub ject was restudied by us when it became clear that regression of the tumor was closely conditioned by the age factor—a factor which, as previously shown (11, 12), exerts such important effects on the tumor as masking its causative virus and sup pressing its transmissibility by cells and its power to in...

Background: Escherichia coli is one of the most common causative agent of urinary tract infection. In recent years, resistance to cephalosporins has been considerably on the rise due to production of extended spectrum beta-lactamases (ESBLs.( This study was aimed to determine the survey of CTX-M, SHV, TEM, OXA-1, PER-2, and VEB-1 which are the most famous ESBL genes in E. coli isolated from out...
