1. 6. The role of chromatin in the induction and repair of DNA damage

   Författare :Mats Ljungman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA damage; Chromatin; Kromatin; DNA;

   Sammanfattning : The role of chromatin in the induction and repair of DNA damage has a dual nature.The constituent proteins of chromatin protect the DNA against the induction of DNAdamage, while at the same time they reduce the accessibility of DNA to repair enzymes. LÄS MER

3. 7. Application of Mitochondrial DNA Analysis in Contemporary and Historical Samples

   Författare :Maria Lembring; Marie Allen; Niels Morling; Uppsala universitet; []
   Nyckelord :Forensic genetics; Mitochondrial DNA; HVI HVII; Population database; Haplotype; Haplogroup; Ancient DNA; Historical DNA samples; skeletal remains; Vasa museum; Medieval samples; Copernicus; Göring; Genetik; Genetics;

   Sammanfattning : The mitochondrion is a tiny organelle that is the power supplier of the cell and vital to the functioning of the body organs. Additionally it contains a small circular genome of about 16 kb, present in many copies which makes the mitochondrial DNA more viable than nuclear DNA. LÄS MER

4. 8. DNA in centromeres of Chironomus pallidivittatus

   Författare :Ching Liao; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Chironomus; CEN DNA; transposable element; centromere; repetitive DNA; cytogenetics; Genetik; cytogenetik;

   Sammanfattning : The centromeres of most higher eukaryotes are embedded within large regions of constitutive heterochromatin and consist of large quantities of highly repetitive DNA. Transposable elements are also found in these regions. LÄS MER

5. 9. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

   Författare :Hans Gustafsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

   Sammanfattning : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms. LÄS MER

7. 10. 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
