  1. 1. Deciphering sequence data : A multivariate approach

    Författare :Maria Sandberg Hiltunen; Michael Sjöström; Svante Wold; Lars Ståhle; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Principal properties; amino acids; nucleotides; tRNA; DNA; multivariate data analysis; sequence analysis; QSAR; quantitative sequence activity relationships;

    Sammanfattning : In this thesis, attention has been focused on the quantitative description of nucleic acids, proteins and peptides. The strategy was to use multivariate chemometrical methods for improving the understanding of the complex structural codes of these kinds of biological molecules. LÄS MER

  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. Single DNA Molecule Analysis – New Tools for Medical Diagnosis

    Författare :My Nyblom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical DNA mapping; DNA damage; DNA; single-molecule analysis; fluorescence microscopy; antibiotic resistance; nanofluidics; genetics;

    Sammanfattning : The DNA molecule, the blueprint of life, contains an enormous amount of information. The information is coded by the combination of four bases; adenine, cytosine, guanine, and thymine, that, together with the sugar-phosphate backbones, make up the DNA double helix. LÄS MER

  5. 4. DNA Interaction Dynamics of Ruthenium(II) Complexes

    Författare :Fredrik Westerlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; ruthenium; polarized spectroscopy; threading; sequence selectivity; photophysics; binding kinetics; DNA; intercalation;

    Sammanfattning : DNA-binding of small synthetic ligands is of great importance in a number of different applications, from medicine to molecular biology. This thesis focuses on interactions between DNA and ruthenium(II) complexes, in particular the dimers [µ-bidppz(L)4Ru2]4+ (L=1,10-phenanthroline (P) or L=2,2-bipyridine (B)). LÄS MER

  7. 5. Structural Requirements for Selective DNA Binding - Studies on Mono- and Binuclear Ruthenium Complexes

    Författare :Johanna Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; enantioselectivity; sequence selectivity; spectroscopy; threading intercalation; calorimetry; kinetics; DNA; cell studies;

    Sammanfattning : Ever since the discovery of the role of DNA as the template for protein synthesis, efforts have been made to develop DNA targeted drugs. One of the major challenges in the design of DNA binding drugs is to achieve selective binding to specific DNA sequences, which is crucial to avoid side effects. LÄS MER
