  2. 1. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Profilin : From the Cell Edge into the Nucleus

    Author : Sara Sadi; Roger Karlsson; Maria Vartiainen; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; profilin; actin; microfilament system; nucleus; SRF; MRTF; MAL; transcription; microtubules; Cell Biology; cellbiologi;

    Abstract : Internal and external signaling dependent changes in cell behavior are directly linked to force-generating remodeling of the actin microfilament system which is juxtaposed to the inside of the plasma membrane. This dynamic filament system is involved in many processes in the cytoplasm and the nucleus of eukaryotic cells. READ MORE

  7. 5. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

    Author : Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. READ MORE
