   Sammanfattning : This thesis presents a comprehensive phylogenetic and taxonomic study of an acoel subgroup, the Childiidae. Members of this taxon are characterized by well-developed male copulatory organs with conical/cylindrical stylets. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

4. 3. 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. Molecular Cloning and Functional Characterization of Factors Involved in Post-transcriptional Gene Expression

   Författare :Shao-Bo Jin; Lars Wieslander; Maria Carmo-Fonseca; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene expression; pre-mRNA processing; pre-rRNA processing; Molecular biology; Molekylärbiologi;

   Sammanfattning : Gene expression in the eukaryotic cell is a fundamental cellular process, which consists of several distinct steps but extensively coupled to each other. From site of transcription in the nucleus to the cytoplasm, both mRNA and rRNA are associated with a proper set of proteins. LÄS MER

7. 5. Microbial DNA Sequencing in Environmental Studies

   Författare :Yue Hu; Anders Andersson; Jürg Logue; Joakim Lundeberg; Marja Tiirola; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA sequencing; Metabarcoding; Microbial ecology; Baltic Sea; Microbial community; Illumina; Oxford Nanopore; Source tracking; Stormwater; Bioteknologi; Biotechnology;

   Sammanfattning : The field of microbial ecology has just entered a new era of rapid technological development and generation of big data. The high-throughput sequencing techniques presently available provide an opportunity to extensively inventorize the blueprints of life. LÄS MER
