  2. 1. Intelligent Nucleic Acid Interactions with Peptide Nucleic Acid (PNA) and Recombination Enzyme RecA

    Author : Pernilla Wittung; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence; RecA; homologous recombination; circular dichroism; DNA analogs; -anti-BPDE; spectroscopy; PNA; DNA-protein interactions;

    Abstract : The work presented in this thesis focuses on interactions between nucleic-acids in biological systems, particularly interactions of the promising drug-candidate peptide nucleic acid (PNA), and on protein-DNA intermediates during recombination. Several experimental techniques, mainly circular dichroism and fluorescence spectroscopy, have been used to characterize the interactions of interest. READ MORE

  4. 2. Aspects of DNA Strand Exchange: Recombination Proteins and Model System Studies

    Author : Karolin Frykholm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA strand exchange; cationic liposome; Rad51; Site-Specific Linear Dichroism; RecA; molecular crowding;

    Abstract : DNA recombination is of fundamental importance to all living cells; it is part of the DNA repair machinery and a means to generate genetic diversity. DNA strand exchange, the exchange of strands between homologous DNA molecules, is the central reaction of the recombination process. READ MORE

    Abstract : 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. READ MORE
