  1. 1. Amelioration of Horizontally Transferred Genes

    Author : Torbjörn Karfunkel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transposoner; horisontell genöverföring; dna; bakterier; plasmider;

    Abstract : The importance of Horizontal (Lateral) Gene Transfer has attracted much attention during the last few decades. It is a very important factor in bacterial evolution and ecology, and it has great implications on human life as well. READ MORE

  3. 3. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    Author : Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. READ MORE

  4. 4. Students’ meaning-making of epigenetic visual representations : An exploration within and between levels of biological organization

    Author : Annika Thyberg; Konrad Schönborn; Niklas Gericke; Clas Olander; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biological organization levels; Genetics education; Learning progression; Meaning-making of epigenetics; Secondary school; Visual representations; Yo-yo reasoning; Biology; Biologi;

    Abstract : This thesis explores lower secondary students’ meaning-making of epigenetic visual representations within and between biological organization levels. Data obtained from five focus group discussions where students indicated and reasoned about eight epigenetic visual representations were explored. READ MORE

  5. 5. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

    Author : Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

    Abstract : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. READ MORE
