  • A Viewpoint of Aspects of a History of Genetics: an Autobiography
    12. The Postgraduate Medical School,London University. The Head of the Bacteriology Department at the PGMS(later the Royal PGMS) was Professor Lord(Trevor) Stamp who did'nt seem to bother what research I did so long as I did something. My closest colleague was Dr.Denny Mitchison(Lecturer),one of the three biologist sons of authoress Naomi Mitchison and nephew of J.B.S.Haldane,whose main interest was typing tubercle bacilli under MRC!auspices. In addition there were at least two non-tenured medical graduates on the staff. My only departmental responsibilities were to take my turn at clinical bacteriology which amounted to the mornings of one week in every three or four,and to share in teaching the bacteriology course for the Diploma in Clinical Pathology which occupied me for not more than a few weeks in the year. There was,in fact,a positive obligation to spend at least half one's time at research. I decided to return to the mechanism of somatic phase variation in S.enteritidis,but had begun to realise the potentiafities of genetic analysis inherent in the recent discovery by Lederberg and Tatum(1946) of conjugation in Escherichia coli ,and wondered if Salmonella also could conjugate. But it was clear that I should first become acquainted with the phenomenon in --E.coli. Towards the end of 1950 I went on a bacterial chemistry course at Cambridge,organized by Prof.E.H.Gale,and there met Luca Cavalli(later Cavalli-Sforza) who had worked with Joshua Lederberg on conjugation at Wisconsin and,being mainly interested in population genetics,was currently a visitor in Prof.R.A.Fisher's Department of Mathematics.

This 0066-4197/07/1201-0001$20.00 resulted in a cyclic permutation of gene order going from phage to prophage. This contrasted with integration models current at the time, which postulated that the prophage was not inserted into the continuity of the chromosome but rather laterally attached or synapsed with it. This chapter summarizes some of the steps leading up to the model including especially the genetic characterization of specialized transducing phages (λgal ) by recombinational rescue of conditionally lethal mutations.

  • Sequence Divergence Impedes Crossover More Than Noncrossover Events During Mitotic Gap Repair in Yeast
    Copyright Ó 2008 by the Genetics Society of America DOI: 10.1534/genetics.108.090233 Sequence Divergence Impedes Crossover More Than Noncrossover Events During Mitotic Gap Repair in Yeast Caroline Welz-Voegele and Sue Jinks-Robertson1 Department of Molecular Genetics and Microbiology, Duke University Medical Center, Durham, North Carolina 27710 Manuscript received April 11, 2008 Accepted for publication May 8, 2008 ABSTRACT Homologous recombination between dispersed repeated sequences is important in shaping eukaryotic genome structure, and such ectopic interactions are affected by repeat size and sequence identity. A transformation-based, gap-repair assay was used to examine the effect of 2% sequence divergence on the efficiency of mitotic double-strand break repair templated by chromosomal sequences in yeast. Because the repaired plasmid could either remain autonomous or integrate into the genome, the effect of sequence divergence on the crossover–noncrossover (CO–NCO) outcome was also examined. Finally, proteins important for regulating the CO–NCO outcome and for enforcing identity requirements during recombination were examined by transforming appropriate mutant strains. Results demonstrate that the basic CO–NCO outcome is regulated by the Rad1-Rad10 endonuclease and the Sgs1 and Srs2 helicases, that sequence divergence impedes CO to a much greater extent than NCO events, that an intact mismatch repair system is required for the discriminating identical and nonidentical repair templates, and that the Sgs1 and Srs2 helicases play additional, antirecombination roles when the interacting sequences are not identical. ECOMBINATION is a high-fidelity process that persed throughout the genome. Such ectopic inter- R copies information from one DNA duplex to re- actions are important for shaping genome structure, pair single- or double-strand discontinuities in another with NCO events likely driving the concerted evolution DNA duplex (reviewed by Krogh and Symington of multigene families and COs leading to various types 2004).

    Barbara McClintock’s World Timeline adapted from Dolan DNA Learning Center exhibition 1902-1908 Barbara McClintock is born in Hartford, Connecticut, the third of four children of Sarah and Thomas Henry McClintock, a physician. She spends periods of her childhood in Massachusetts with her paternal aunt and uncle. Barbara at about age five. This prim and proper picture betrays the fact that she was, in fact, a self-reliant tomboy. Barbara’s individualism and self-sufficiency was apparent even in infancy. When Barbara was four months old, her parents changed her birth name, Eleanor, which they considered too delicate and feminine for such a rugged child. In grade school, Barbara persuaded her mother to have matching bloomers (shorts) made for her dresses – so she could more easily join her brother Tom in tree climbing, baseball, volleyball, My father tells me that at the and football. age of five I asked for a set of tools. He My mother used to did not get me the tools that you get for an adult; he put a pillow on the floor and give got me tools that would fit in my hands, and I didn’t me one toy and just leave me there. think they were adequate. Though I didn’t want to tell She said I didn’t cry, didn’t call for him that, they were not the tools I wanted. I wanted anything. real tools not tools for children. 1908-1918 McClintock’s family moves to Brooklyn in 1908, where she attends elementary and secondary school. In 1918, she graduates one semester early from Erasmus Hall High School in Brooklyn.

Library of Congress Catalog Card Number 87-619898 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, DC 20402-9325 (order form can be found in the back of this report) Foreword For the past 2 years, scientific and technical journals in biology and medicine have extensively covered a debate about whether and how to determine the function and order of human genes on human chromosomes and when to determine the sequence of molecular building blocks that comprise DNA in those chromosomes. In 1987, these issues rose to become part of the public agenda. The debate involves science, technol- ogy, and politics. Congress is responsible for ‘(writing the rules” of what various Federal agencies do and for funding their work. This report surveys the points made so far in the debate, focusing on those that most directly influence the policy options facing the U.S. Congress, The House Committee on Energy and Commerce requested that OTA undertake the project. The House Committee on Science, Space, and Technology, the Senate Com- mittee on Labor and Human Resources, and the Senate Committee on Energy and Natu- ral Resources also asked OTA to address specific points of concern to them. Congres- sional interest focused on several issues: ● how to assess the rationales for conducting human genome projects, ● how to fund human genome projects (at what level and through which mech- anisms), ● how to coordinate the scientific and technical programs of the several Federal agencies and private interests already supporting various genome projects, and ● how to strike a balance regarding the impact of genome projects on international scientific cooperation and international economic competition in biotechnology.

    Barbara McClintock Lee B. Kass and Paul Chomet Abstract Barbara McClintock, pioneering plant geneticist and winner of the Nobel Prize in Physiology or Medicine in 1983, is best known for her discovery of transposable genetic elements in corn. This chapter provides an overview of many of her key findings, some of which have been outlined and described elsewhere. We also provide a new look at McClintock’s early contributions, based on our readings of her primary publications and documents found in archives. We expect the reader will gain insight and appreciation for Barbara McClintock’s unique perspective, elegant experiments and unprecedented scientific achievements. 1 Introduction This chapter is focused on the scientific contributions of Barbara McClintock, pioneering plant geneticist and winner of the Nobel Prize in Physiology or Medicine in 1983 for her discovery of transposable genetic elements in corn. Her enlightening experiments and discoveries have been outlined and described in a number of papers and books, so it is not the aim of this report to detail each step in her scientific career and personal life but rather highlight many of her key findings, then refer the reader to the original reports and more detailed reviews. We hope the reader will gain insight and appreciation for Barbara McClintock’s unique perspective, elegant experiments and unprecedented scientific achievements. Barbara McClintock (1902–1992) was born in Hartford Connecticut and raised in Brooklyn, New York (Keller 1983). She received her undergraduate and graduate education at the New York State College of Agriculture at Cornell University. In 1923, McClintock was awarded the B.S.
