  3. 2. Development of benzoquinoquinoxaline derivatives as triplex-specific probes : Recognition of DNA structures at repeats sequences

    Författare :Helen Bergquist; Rula Zain; Keith Fox; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triplex; H-DNA; BQQ; BQQ-OP; BQQ-Bodipy; triplet repeat; DNA; non-B-DNA; pkd1; frataxin; Friedreich s ataxia; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Repeat sequences are associated with several human diseases, such as Friedreich’s ataxia, polycystic kidney disease and cancer. These sequences can form non-B-DNA structures, including triplex (H-DNA) DNA, and are associated with genomic instability and altered gene expression. LÄS MER

  4. 3. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

    Författare :Cecilia Leal; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

    Sammanfattning : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. LÄS MER

  5. 4. Overstretching short DNA – Single-molecule force spectroscopy studies

    Författare :Niklas Bosaeus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA stretching; mechanical properties of DNA; single molecule; optical tweezers; DNA structure;

    Sammanfattning : Structural deformation of DNA has a central role in many biological processes. It occurs, for example, during replication, transcription, and regulation of the activity of the genome. To understand these fundamental processes it is necessary to have a detailed knowledge of the mechanical properties of DNA. LÄS MER

  7. 5. Structure of eukaryotic DNA polymerase epsilon and lesion bypass capability

    Författare :Nasim Sabouri; Erik Johansson; Lars Thelander; Ola Hammarsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA polymerase epsilon; DNA replication; Okazaki fragment; Translesion synthesis; DNA lesion; dNTP; Biochemistry; Biokemi;

    Sammanfattning : To transfer the information in the genome from mother cell to daughter cell, the DNA replication must be carried out only once and with very high fidelity prior to every cell division. In yeast there are several different DNA polymerases involved in DNA replication and/or DNA repair. LÄS MER
