  1. 11. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species

    Författare :Ramprasad Neethiraj; Christopher Wheat; Sören Nylin; Mathieu Joron; Stockholms universitet; []

    Sammanfattning : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.

  3. 12. Environmental Contaminants, Recombination and Cancer : Investigations on the molecular mechanisms of spontaneous and induced recombination in the hprt gene of Chinese hamster cells

    Författare :Thomas Helleday; Mark Meuth; Stockholms universitet; []
    Nyckelord :toxikologisk genetik; Genetic Toxicology;

    Sammanfattning : Recombination results in rearrangement of the genetic material contained in the chromosomes inherited from the mother and father and this process is also involved in repairing damage to the genome. Occasionally, the machinery that performs recombination malfunctions and this may lead to illegitimate recombination events which inactivate tumor suppressor genes or activate protooncogenes.

  5. 14. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring

    Författare :Safdar Ali; Reinhold Schuch; José R. Crespo López-Urrutia; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Highly charged ions; Atomic processes; Atomic data; Electron-ion recombination; Plasmas; fysik; Physics;

    Sammanfattning : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. LÄS MER

  7. 15. Mitotic recombination in mammalian cells

    Författare :Catherine Arnaudeau; Harry Vrieling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; toxikologisk genetik; Genetic Toxicology;

    Sammanfattning : Recombination is usually defined as the exchange of genetic material between two strands or regions of nucleic acids. This process occurs in all known organisms and is highly conserved, especially among higher eukaryotes. Various types of recombination, involving homologous or non-homologous nucleic acid sequences, are known to exist. LÄS MER
