  1. 6. Bacterial DNA repair and molecular search

    Författare :Arvid H. Gynnå; Johan Elf; Stephen Kowalczykowski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA repair; DNA damage; homologous recombination; homologous repair; recombination; RecA; I-SceI; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. LÄS MER

  3. 7. Genomic studies of sex differences : On mutations, recombination, and sexual antagonism in songbirds

    Författare :Hongkai Zhang; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sex differences; mutation; recombination; sexual conflict; sexual antagonism; sexually antagonistic selection; Great reed warbler; Acrocephalus arundinaceus;

    Sammanfattning : Many organisms have separate sexes, i.e., males and females. The presence of separate sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex differences in morphology, physiology, and behaviours. LÄS MER

  4. 8. Electron Recombination with Small Molecular Ions

    Författare :Johanna Brinne Roos; Hans Ågren; Åsa Larson; Hans Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissociative recombination; ion-pair formation; resonant states; wave packet; molecular dynamics; electron scattering; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : In this thesis I have theoretically studied electron recombination processes with small molecular ions. In these kind of processes resonant states are involved. To calculate the potential energy for these states as a function of internuclear distance, structure calculations and scattering calculations have to be performed. LÄS MER

  5. 9. Dissociative Recombination of Astrochemically Interesting Ions

    Författare :Mathias Hamberg; Wolf Geppert; Mats Larsson; Stephan Schlemmer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dissociative Recombination; Astrochemistry; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : In this thesis the major work described concerns experimental determination of the dissociative recombination (DR) reaction for several molecular ions of astrochemical interest. DR is the process where an electron recombines with a molecular ion to form an excited neutral that disintegrates into two or more neutral fragments to release the gained excess energy. LÄS MER

  7. 10. DNA-protein complexes : experimental studies of structure and interactions in solution

    Författare :Per Hagmar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA binding domain; methylene blue; flow linear dichroism; recombination protein A; RecA; chromatin structure; recombination; electric linear dichroism; chromatin; glucocorticoid receptor;
