  4. 12. Functional and structural properties of eukaryotic DNA polymerase epsilon

    Author : Olga Chilkova; Erik Johansson; Per Elias; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; eukaryotic DNA replication; DNA polymerase epsilon; protein-DNA interaction; Biochemistry; Biokemi;

    Abstract : In eukaryotes there are three DNA polymerases which are essential for the replication of chromosomal DNA: DNA polymerase alpha (Pol alpha), DNA polymerase delta (Pol delta) and DNA polymerase epsilon (Pol epsilon). In vitro studies of viral DNA replication showed that Pol alpha and Pol delta are sufficient for DNA replication on both leading and lagging DNA strands, thus leaving the function of Pol epsilon unknown.

  5. 13. DNA Interactions with Chiral Polyaza-aromatic Ruthenium(II) Complexes

    Author : Per Lincoln; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phenanthroline; binding geometry; binding isotherm; DNA; dppz; linear dichroism; intercalation; ruthenium; cooperative binding;

    Abstract : The binding to DNA of a series of chiral ruthenium complexes is studied with optical spectroscopy techniques, including isotropic absorption, linear dichroism (LD) and emission anisotropy as well as steady-state and time-resolved luminescence. The thesis focuses on the ìlight-switchî complex [Ru(phen)2dppz]2+ which binds to DNA by intercalation and luminesces when bound to DNA but not in pure buffer solution (phen=1,10-phenanthroline; dppz=dipyrido[3,2-a:2',3'-c]phenazine).

  6. 14. Ribonucleotide reductase and DNA damage

    Author : Pelle Håkansson; Lars Thelander; Claes Gustafsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ribonucleotide reductase; DNA damage; dNTP pools; Medical cell biology; Medicinsk cellbiologi;

    Abstract : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. READ MORE

  7. 15. Arrayed identification of DNA signatures

    Author : Max Käller; Lundeberg Joakim; Mats Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apyrase; allele-specific extension; competitive hybridization; DNA sequencing; genotyping; human papillomavirus HPV ; MC1R; microarray; mutation; p53; protease; Bioengineering; Bioteknik;

    Abstract : In this thesis techniques are presented that aim to determine individual DNA signatures by controlled synthesis of nucleic acid multimers. Allele-specific extension reactions with an improved specificity were applied for several genomic purposes. Since DNA polymerases extend some mismatched 3’-end primers, an improved specificity is a concern. READ MORE
