  1. 1. The consequences of DNA lesions for mitochondrial DNA maintenance

    Author : Josefin M. E. Forslund; Sjoerd Wanrooij; Nasim Sabouri; Erik Johansson; Claes Gustafsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; mitochondrial DNA; DNA replication; DNA lesions; DNA polymerase γ; ribonucleotide incorporation; medicinsk biokemi; Medical Biochemistry;

    Abstract : Eukaryotic cells have their own energy-producing organelles called mitochondria. The energy is stored in the adenosine triphosphate (ATP) molecule and is produced via the oxidative phosphorylation process inside the mitochondria. Thirteen of the essential proteins required for this process are encoded on the mitochondrial DNA (mtDNA). READ MORE

  2. 2. Replication Dynamics in the DNA Damage Response

    Author : Petra Groth; Thomas Helleday; Geroge Iliakis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA replication; homologous recombination; DNA double strand-breaks; ionizing radiation; alkylating agents; NATURAL SCIENCES; NATURVETENSKAP; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Abstract : Faithful DNA replication is essential and the induction of replication stress may have profound effects on genomic integrity. This is demonstrated by the formation of DNA double strand breaks (DSBs), considered to be the most toxic DNA lesions, at stalled replication forks. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. Structure of eukaryotic DNA polymerase epsilon and lesion bypass capability

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

    Abstract : 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. READ MORE

  5. 5. DNA precursor asymmetries, Mismatch Repair and their effect on mutation specificity

    Author : Robert Buckland; Andrei Chabes; Juan Méndez; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA Replication Fidelity; Mutations; dNTP pools; Mismatch Repair; Checkpoint; Ribonucleotide Reductase; Msh2; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

    Abstract : In order to build any structure, a good supply of materials, accurate workers and quality control are needed. This is even the case when constructing DNA, the so-called “Code of Life.” For a species to continue to exist, this DNA code must be copied with incredibly high accuracy when each and every cell replicates.
