The last part of the DNA series, but this post in particular, successfully confer the sense of beauty, excitement and awe when a model "clicks" in place which I recognize well albeit in much smaller contexts. Again, well done! Btw, it seems to be an excellent example of the common observation that the most elegant expressive models must rely on simplicity - the three stranded models came up short.
Reports the results of a citation study on Watson and Crick's paper announcing the discovery of the double helix structure of DNA. The paper has been cited more than 2, times since , and there is no sign of any obsolescence to this article. An analysis was undertaken of the journals in which the citations appeared, and of mistakes in the bibliographic citations provided by citing articles. Watson and Crick themselves have only cited their own paper twice since An analysis was also undertaken of the reasons why the paper was cited; citing articles were identified and read. The reasons for citing were then categorised using the Oppenheim and Renn method. Compared to earlier studies, it was found that a greater proportion of citations were for historical reasons, a smaller proportion of citing articles were actively using the Watson and Crick article, and a similar, but low proportion were criticising the Watson and Crick article.
Skip navigation. In , Oswald T. Avery and his group at Rockefeller University in New York City, New York published experimental evidence that DNA contained the biological factors called genes that dictate how organisms grow and develop. The model that Watson and Crick presented connected the concept of genes to heredity, growth, and development. At the time, Watson was a twenty-three-year-old postdoctoral researcher from the United States and Crick, at the age of thirty-five, was a PhD student at the University of Cambridge. They frequently ate lunch together and discussed their work and the work of others in the laboratory. Eventually, senior members of the laboratory gave Watson and Crick an office space to share.
Their paper in Nature in laid the groundwork for understanding DNA structure and functions. Together with Maurice Wilkins , they were jointly awarded the Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the helical structure of DNA. He is widely known for the use of the term " central dogma " to summarise the idea that once information is transferred from nucleic acids DNA or RNA to proteins, it cannot flow back to nucleic acids. In other words, the final step in the flow of information from nucleic acids to proteins is irreversible.

Watson and Crick raced to find the structure before anyone else. They were competing with Linus Pauling, who had earlier discovered the alpha-helical structure of some protein molecules. While Watson and Crick were still working on their model, Pauling published a paper suggesting a triple-helical structure for DNA. Others quickly realized that the model was chemically flawed. Watson and Crick used paper cutouts of the bases and metal scraps from a machine shop to come up with their own model. Their word paper, published in Nature , concluded, famously, "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.
Watson and F. Crick 1 April 25, 2 , Nature 3 , , We wish to suggest a structure for the salt of deoxyribose nucleic acid D. This structure has novel features which are of considerable biological interest. A structure for nucleic acid has already been proposed by Pauling 4 and Corey 1. They kindly made their manuscript available to us in advance of publication.

Они буквально пожирали ее тело. Новая волна паники охватила Сьюзан. Хейл всей тяжестью своего тела придавил ее ноги, холодно следя за каждым ее движением.
Подобно своим природным аналогам они преследуют одну цель - внедриться в организм и начать размножаться. В данном случае организмом является ТРАНСТЕКСТ. Чатрукьяна всегда изумляло, что АНБ никогда прежде не сталкивалось с проблемой вирусов.
Джабба полагает, что… - Вы ему звонили. - Да, сэр, я… - Джаббе? - Фонтейн гневно поднялся. - Какого черта вы не позвонили Стратмору. - Мы позвонили! - не сдавалась Мидж.
На номерном знаке авто была надпись МЕГАБАЙТ в обрамлении сиреневой неоновой трубки. Ранняя юность Грега Хейла не была омрачена криминальными историями, поскольку он провел ее в Корпусе морской пехоты США, где и познакомился с компьютером. Он стал лучшим программистом корпуса, и перед ним замаячила перспектива отличной военной карьеры.
Бринкерхофф кивнул. Это было одним из крупнейших достижений Стратмора.
