DNA seen through the eyes of a coder or If you are a hammer, everything looks like a nail This is just some rambling by a computer programmer about DNA. I'm not a molecular geneticist. If you spot the inevitable mistakes, please mail me (bert hubert) at ahu@ds9a.nl. I'm not trying to force my view unto the DNA - each observation here is quite 'uncramped'.

Reprinted with permission from Nature magazine A Structure for Deoxyribose Nucleic Acid J. D. Watson and F. H. C. Crick (1) April 25, 1953 (2), Nature (3), 171, 737-738 We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). A structure for nucleic acid has already been proposed by Pauling (4) and Corey1. . (1) We believe that the material which gives the X-ray diagrams is the salt, not the free acid. . (2) Some of the van der Waals distances appear to be too small. Another three-chain structure has also been suggested by Fraser (in the press). The structure is an open one, and its water content is rather high.
The novel feature of the structure is the manner in which the two chains are held together by the purine and pyrimidine bases. If it is assumed that the bases only occur in the structure in the most plausible tautomeric forms (that is, with the keto rather than the enol configurations) it is found that only specific pairs of bases can bond together.

Latest Update: 25-Jan-2014 by George (email). Genetics and violence - Wikipedia, the fre. The field of psychology has been greatly influenced by the study of genetics. Decades of research has demonstrated that both genetic and environmental factors play a role in a variety of behaviors in humans and animals (e.g. Grigorenko & Sternberg, 2003).
The genetic basis of aggression, however, remains poorly understood. Aggression is a multi-dimensional concept, but it can be generally defined as behavior that inflicts pain or harm on another. Genetic-developmental theory states that individual differences in a continuous phenotype result from the action of a large number of genes, each exerting an effect that works with environmental factors to produce the trait.[1] This type of trait is influenced by multiple factors making it more complex and difficult to study than a simple Mendelian trait (one gene for one phenotype). History[edit] The XYY genotype first gained wide notoriety in 1968 when it was raised as a part of a defense in two murder trials in Australia and France.
