  1. 1. Role of yeast DNA polymerase epsilon during DNA replication

    Författare :Isabelle Isoz; Erik Johansson; Juhani Syväoja; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; DNA polymerase epsilon; eukaryotic DNA replication; fidelity; leading strand; Dpb2; Biochemistry and clinical chemistry; Biokemi och klinisk kemi;

    Sammanfattning : Each cell division, the nuclear DNA must be replicated efficiently and with high accuracy to avoid mutations which can have an effect on cell function. There are three replicative DNA polymerases essential for the synthesis of DNA during replication in eukaryotic cells. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Herpes Simplex Virus 1 DNA replication and its role in recombination and transcription

    Författare :Ka-Wei Tang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Herpes Simplex Virus 1; DNA replication; DNA recombination; Transcription;

    Sammanfattning : Herpes simplex virus 1 (HSV-1) is one of nine different herpesvirus infecting man. They are all capable of establishing a life-long latent state following the primary infection. HSV-1 as well as other herpesviruses may reactivate from the latent state and give rise to a productive infection with clinical symptoms or asymptomatic shedding. LÄS MER

  7. 5. Functional and structural properties of eukaryotic DNA polymerase epsilon

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

    Sammanfattning : 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.
