  1. 11. Novel insights into protist diversity and niche adaptation using single cell transcriptomics

    Författare :Henning Onsbring; Thijs J. G. Ettema; Alastair Simpson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protists; microbial eukaryotes; cultivation-independent methods; single-cell RNA sequencing; phylogenomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Protists are a polyphyletic group of microbes that represents the vast majority of eukaryotic diversity. Despite this, most sequencing efforts targeting eukaryotes have been focused on animals, fungi and plants. LÄS MER

  3. 12. Structural and functional studies of the ribosomes : a closer look at expansion segments and translational dynamics in eukaryotes

    Författare :Sofia L. Larsson; Alexei A. Bogdanov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosomer; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : The ribosome is the basic machinery for protein synthesis in all living cells. In the last decade, there has been an explosion of structural information on the ribosome. The eukaryotic ribosome is larger than the prokaryotic counterpart and contains several extra features, even though they have similar core structures. LÄS MER

  4. 13. Elongation factor 2: A key component of the translation machinery in eukaryotes : Properties of yeast elongation factor 2 studied in vivo

    Författare :Galyna Bartish; Odd Nygård; Suparna Sanyal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elongation factor 2; yeast; ribosome; phosphorylation; Switch I; site-directed mutagenesis; functional complementation; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Synthesis of proteins is performed by the ribosome, a large ribonucleoprotein complex. Apart from the ribosome, numerous protein factors participate in this process. Elongation factor 2 (eEF2) is one of these factors. eEF2 is an essential protein with a mol. LÄS MER

  5. 14. 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

  7. 15. Genomic and evolutionary exploration of Asgard archaea

    Författare :Eva F. Caceres; Thijs J. G. Ettema; Simonetta Gribaldo; Uppsala universitet; []
    Nyckelord :archaea; Asgard; eukaryogenesis; metagenomics; genome binning; phylogenetics; phylogenomics; comparative genomics; gene tree-species tree reconciliation; ancestral reconstruction; long-read metagenomics;

    Sammanfattning : Current evolutionary theories postulate that eukaryotes emerged from the symbiosis of an archaeal host with, at least, one bacterial symbiont. However, our limited grasp of microbial diversity hampers insights into the features of the prokaryotic ancestors of eukaryotes. LÄS MER
