  1. 1. Ribonucleotides in DNA - Application in genome-wide DNA polymerase tracking and physiological role in eukaryotes

    Författare :Katrin Kreisel; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ribonucleotides; DNA instability; DNA polymerase eta; nuclear DNA; mitochondrial DNA;

    Sammanfattning : The genetic code in the eukaryotic cell is stored in the form of DNA, which is more resistant to hydrolysis than RNA. Replication fidelity and DNA repair mechanisms are in place to ensure genomic integrity to preserve the information encoded. LÄS MER

  3. 2. Stability of bacterial DNA in relation to microbial detection in teeth

    Författare :Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

    Sammanfattning : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. LÄS MER

  4. 3. DNA Analysis of PCR-Inhibitory Forensic Samples

    Författare :Johannes Hedman; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylase; statistical modelling; principal components analysis; PCR inhibitors; PCR inhibition; forensic DNA analysis; DNA polymerase blend; DNA polymerase; crime scene samples;

    Sammanfattning : DNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. LÄS MER

  5. 4. 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

  7. 5. Epstein-Barr virus gene methylation and variation in latency

    Författare :Kerstin I Falk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epstein-Barr virus is a human herpesvirus and approximately 95 % of the adults carry the virus in a latent form. EBV has been implicated in the pathogenesis of human malignancies such as Burkitt's lymphoma and nasopharyngeal carcinoma. DNA methylation is one of the mechanisms that is involved in control of gene expression in viruses. LÄS MER
