  1. 11. Molecular insights into primer removal during mtDNA replication

    Författare :Ali Al-Behadili; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; Mitochondrial DNA replication; DNA replication; Primer removal; RNase H1; Primer formation; Replication initiation; mitochondrial diseases;

    Sammanfattning : Mitochondria are vital for cell survival, and the primary producers of ATP, the energy currency used for various metabolic processes. Mitochondria are unique from other cellular compartments because they have their own genomes of circular small double-stranded DNA (mtDNA) of approximately 16. LÄS MER

  2. 12. Molecular insights into mitochondrial DNA replication

    Författare :Javier Miralles Fusté; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mitochondria are organelles found in eukaryotic cells. These organelles produce most of the adenosine triphosphate that cells use as a source of energy. Mitochondria contain their own genomic material, a circular DNA genome (mtDNA) that encodes subunits of the respiratory chain complexes and RNA components needed for mitochondrial translation.

  3. 13. Molecular mechanisms of mitochondrial DNA replication

    Författare :Teresa Holmlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mitochondria; mtDNA; replication; helicase; TWINKLE; POLgamma; POLgammaB; mtSSB; adPEO;

    Sammanfattning : Mitochondria are the energy producing organelles of eukaryotic cells. The organelle has its own genome, the mitochondrial DNA (mtDNA) that encodes 13 subunits of the respiratory chain (RC) complexes, two rRNAs and 22 tRNAs. LÄS MER

  4. 14. Organization and regulation of mitochondrial gene expression

    Författare :Roger Salvatori; Martin Ott; Benoit Kornmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitochondrial gene expression; post-transcriptional regulation; mitochondrial ribosome; protein-protein proximity; BioID; feedback loop; Biochemistry; biokemi;

    Sammanfattning : Mitochondria possess their own genome, remnant of the ancestral eubacterial endosymbiont DNA. This mitochondrial genome encodes mostly few key subunits of the respiratory chain. In order to synthesize these few proteins, mitochondria contain a complete gene expression machinery. LÄS MER

  5. 15. Life without mitochondrial DNA : studies of transgenic mice

    Författare :Jianming Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :mitochondrial disease; mitochondrial DNA mtDNA ; mitochondrial transcripton factor A Tfam ; cre-loxP; conditional knockout; transgenic; mitochondrial cardiomyopathy; apoptosis;

    Sammanfattning : Mitochondrial DNA (mtDNA) is a closed circular DNA genome that resides in the mitochondrial network. Mutations of mtDNA cause spontaneous and hereditary disorders known as mitochondrial diseases. Mitochondrial transcription factor A (Tfam) is a key factor for transcription of mtDNA in vitro. LÄS MER
