  1. 6. Regulation of Human Mitochondrial DNA Replication and Transcription

    Författare :Majda Mehmedovic; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; mtDNA; replication; transcription; TFAM;

    Sammanfattning : Mitochondria are organelles in eukaryotic cells, which through oxidative phosphorylation (OXPHOS) produce most of the ATP used to drive cellular processes. The organelle contains its own genetic material, mitochondrial DNA (mtDNA), which encodes 13 key components of the OXPHOS machinery. LÄS MER

  3. 7. Activity of tumor-antigens in polyomavirus replication

    Författare :Hongyun Li; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Tumor-Antigens; DNA Replication; Cell-cycle; Phosphorylation; J-domain; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Polyomavirus replication needs an active cell environment, and the viral DNA replication is cell cycle regulated. Tumor antigens (T-antigens) of mouse polyomavirus, especially large T-antigen, are necessary for the replication. LÄS MER

  4. 8. Studies on rotavirus replication

    Författare :Alexis Fuentes; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Rotavirus is the leading cause of dehydrating diarrhea in infants and young children globally. In cells infected with rotavirus SA11 the synthesis of viral RNA and protein predominated already after a few hours. Cellular RNA remained intact, but viral mRNA was preferentially utilised for protein synthesis. LÄS MER

  5. 9. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus

    Författare :Karin Hjort; Patrick Dennis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Cell cycle; Sulfolobus; Archaea; Origin; Replication; SIRV2; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : The third domain of life, Archaea is one of the three main evolutionary lineages together with the Bacteria and the Eukarya domains. The archaea are, despite their prokaryotic cell organisation, more closely related to eukaryotes than to bacteria in terms of the informational pathways (DNA replication, transcription and translation).

  7. 10. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle

    Författare :Mats Walldén; Johan Elf; Peter Graumann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E.coli; cell cycle; replication initiation; transcription factor; gene-regulation; single molecule microscopy; microfluidics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. LÄS MER
