Francis Crick in Molecular Biology
2019 Asia-Pacific Conference on Emerging Technologies and Engineering (ACETE 2019) Francis Crick in Molecular Biology Sun Yongping College of Physic and Electronic Information, Inner Mongolia Normal University, Hohhot, China Keywords: Crick, DNA, Protein, Genetic Codes, Molecular Biology Abstract: This article is a tribute to Francis crick, a biophysicist who passed away on July 28, 2004. Francis crick, James Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for physiology or medicine for discovering the molecular structure of nucleic acids and its significance for information transfer in living material. It is pointed out that the diverse background and unique sensitivity of crick to science enabled him to have great insights into frontier research. He had a special capacity for prudent and logical thinking, which contributed so much to the development of molecular biology. Based on Francis crick’s academic achievements in molecular biology and by virtue of internal history approaches such as concept analysis and literature research, this paper is aimed at revealing the historical contributions of crick in a condensed way and to commemorate his work. 1. Introduction Francis crick (figure 1) was born on June 8, 1916 as an English citizen, and he left the world, aged 88. With lifelong devotion to scientific research, crick is credited as one of the central figures in the molecular revolution that swept through biology in the latter half of the twentieth century [1]. Keen on seeking after and tackling the profound problems, he developed a passion for biology although crick did research in physics at the beginning of his scientific life [2,3]. -
Discovery of DNA Structure and Function: Watson and Crick By: Leslie A
01/08/2018 Discovery of DNA Double Helix: Watson and Crick | Learn Science at Scitable NUCLEIC ACID STRUCTURE AND FUNCTION | Lead Editor: Bob Moss Discovery of DNA Structure and Function: Watson and Crick By: Leslie A. Pray, Ph.D. © 2008 Nature Education Citation: Pray, L. (2008) Discovery of DNA structure and function: Watson and Crick. Nature Education 1(1):100 The landmark ideas of Watson and Crick relied heavily on the work of other scientists. What did the duo actually discover? Aa Aa Aa Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher's discovery, other scientists--notably, Phoebus Levene and Erwin Chargaff--carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix. The First Piece of the Puzzle: Miescher Discovers DNA Although few people realize it, 1869 was a landmark year in genetic research, because it was the year in which Swiss physiological chemist Friedrich Miescher first identified what he called "nuclein" inside the nuclei of human white blood cells. (The term "nuclein" was later changed to "nucleic acid" and eventually to "deoxyribonucleic acid," or "DNA.") Miescher's plan was to isolate and characterize not the nuclein (which nobody at that time realized existed) but instead the protein components of leukocytes (white blood cells). -

Francis H. C. Crick: memories of a friend of Francis and Odile The world feels strange without Francis. It is of course full of memories of him. Mostly memories of the charismatic personality, of the brilliant mind, of the great scientist, of the stories of his discoveries in molecular biology. After all, the names of Watson and Crick will be with us as long as Einstein’s and Planck’s. My fondest memories of Francis are of a different kind. I met him at about the time – in ‘76 – when Francis and Odile moved from Cambridge, England to the Salk Institute in La Jolla, California. At the Salk he became a theoretical neuroscientist, following his second passion. After the mystery of life, the mystery of the mind. I saw him at F.O. Schmitt ‘s Neuroscience Research Program meetings. I visited Francis and Odile during the summers in their house on Portugal Place in Cambridge, England, with its golden helix above the front door. I went with them and the Orgels in trips to the desert. I saw him debating about consciousness with various guests at my home. In ‘79, I worked for an intense month at the Salk Institute with him and the late David Marr, trying to understand the connection between the architecture of visual cortex and several intriguing aspects of our visual perception. In those years molecular biology was becoming the dominant science. I remember the difficulty – then, not now -- of getting neuroscience appointments through the well- earned intellectual arrogance of our friends and colleagues in the Department of Biology at MIT. -
Quiet Debut'' of the Double Helix: a Bibliometric and Methodological
Journal of the History of Biology Ó Springer 2009 DOI 10.1007/s10739-009-9183-2 Revisiting the ‘‘Quiet Debut’’ of the Double Helix: A Bibliometric and Methodological note on the ‘‘Impact’’ of Scientific Publications YVES GINGRAS De´partement d’histoire Universite´ du Que´bec a` Montre´al C.P. 8888, Suc. Centre-Ville Montreal, QC H3C-3P8 Canada E-mail: [email protected] Abstract. The object of this paper is two-fold: first, to show that contrary to what seem to have become a widely accepted view among historians of biology, the famous 1953 first Nature paper of Watson and Crick on the structure of DNA was widely cited – as compared to the average paper of the time – on a continuous basis from the very year of its publication and over the period 1953–1970 and that the citations came from a wide array of scientific journals. A systematic analysis of the bibliometric data thus shows that Watson’s and Crick’s paper did in fact have immediate and long term impact if we define ‘‘impact’’ in terms of comparative citations with other papers of the time. In this precise sense it did not fall into ‘‘relative oblivion’’ in the scientific community. The second aim of this paper is to show, using the case of the reception of the Watson–Crick and Jacob–Monod papers as concrete examples, how large scale bibliometric data can be used in a sophisticated manner to provide information about the dynamic of the scientific field as a whole instead of limiting the analysis to a few major actors and generalizing the result to the whole community without further ado. -
DNA: the Timeline and Evidence of Discovery
1/19/2017 DNA: The Timeline and Evidence of Discovery Interactive Click and Learn (Ann Brokaw Rocky River High School) Introduction For almost a century, many scientists paved the way to the ultimate discovery of DNA and its double helix structure. Without the work of these pioneering scientists, Watson and Crick may never have made their ground-breaking double helix model, published in 1953. The knowledge of how genetic material is stored and copied in this molecule gave rise to a new way of looking at and manipulating biological processes, called molecular biology. The breakthrough changed the face of biology and our lives forever. Watch The Double Helix short film (approximately 15 minutes) – hyperlinked here. 1 1/19/2017 1865 The Garden Pea 1865 The Garden Pea In 1865, Gregor Mendel established the foundation of genetics by unraveling the basic principles of heredity, though his work would not be recognized as “revolutionary” until after his death. By studying the common garden pea plant, Mendel demonstrated the inheritance of “discrete units” and introduced the idea that the inheritance of these units from generation to generation follows particular patterns. These patterns are now referred to as the “Laws of Mendelian Inheritance.” 2 1/19/2017 1869 The Isolation of “Nuclein” 1869 Isolated Nuclein Friedrich Miescher, a Swiss researcher, noticed an unknown precipitate in his work with white blood cells. Upon isolating the material, he noted that it resisted protein-digesting enzymes. Why is it important that the material was not digested by the enzymes? Further work led him to the discovery that the substance contained carbon, hydrogen, nitrogen and large amounts of phosphorus with no sulfur. -
Physics Today - February 2003
Physics Today - February 2003 Rosalind Franklin and the Double Helix Although she made essential contributions toward elucidating the structure of DNA, Rosalind Franklin is known to many only as seen through the distorting lens of James Watson's book, The Double Helix. by Lynne Osman Elkin - California State University, Hayward In 1962, James Watson, then at Harvard University, and Cambridge University's Francis Crick stood next to Maurice Wilkins from King's College, London, to receive 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." Watson and Crick could not have proposed their celebrated structure for DNA as early in 1953 as they did without access to experimental results obtained by King's College scientist Rosalind Franklin. Franklin had died of cancer in 1958 at age 37, and so was ineligible to share the honor. Her conspicuous absence from the awards ceremony--the dramatic culmination of the struggle to determine the structure of DNA--probably contributed to the neglect, for several decades, of Franklin's role in the DNA story. She most likely never knew how significantly her data influenced Watson and Crick's proposal. Franklin was born 25 July 1920 to Muriel Waley Franklin and merchant banker Ellis Franklin, both members of educated and socially conscious Jewish families. They were a close immediate family, prone to lively discussion and vigorous debates at which the politically liberal, logical, and determined Rosalind excelled: She would even argue with her assertive, conservative father. Early in life, Rosalind manifested the creativity and drive characteristic of the Franklin women, and some of the Waley women, who were expected to focus their education, talents, and skills on political, educational, and charitable forms of community service. -

Introducción a La Biología Molecular E Historia Del Adn
INTRODUCCIÓN A LA BIOLOGÍA MOLECULAR E HISTORIA DEL ADN Dr. Raúl N. Ondarza Profesor Titular de Bioquímica, Facultad de Medicina, UNAM e Investigador en Ciencias Médicas, Centro de Investigaciones Sobre Enfermedades Infecciosas, INSP ¿QUÉ ES LA BIOLOGIA MOLECULAR ? Según Crick es un término ambiguo que se emplea en dos formas: La primera en un sentido muy general que puede ser entender algún problema biológico a nivel molecular. La segunda forma es más clásica, se refiere a moléculas biológicas de elevado peso molecular; ej. Acidos nucleicos y proteínas. La simplicidad y la universalidad de los mecanismos básicos que operan en Biología, han permitido el avance espectacular de la Biología Molecular, sobre todo en el sentido clásico del término.
