  1. 1. Eukaryotic Ribosome Biogenesis : Focus on the function of the assembly factor Mrd1p

    Författare :Åsa Segerstolpe; Lars Wieslander; Susan Gerbi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; nucleolus; pre-rRNA processing; RNA-binding proteins; Mrd1; Molecular Biology; molekylärbiologi;

    Sammanfattning : The ribosome, the protein factory of the cell, is essential for all life forms. The ribosome is a large RNA-protein machine. It is built in a complex, multi-step process that involves a large number of accessory trans-acting factors and the synthesis consumes a considerable part of the cellular energy. LÄS MER

  5. 4. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Författare :Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []

    Sammanfattning : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.

  7. 5. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes

    Författare :Marika Salonen Sloma; Diarmaid Hughes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. LÄS MER
