  1. 1. Catabolism of Pyrimidines in Yeast

    University dissertation from Department of Biology, Lund University

    Author : Anna Rasmussen; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

    Abstract : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. READ MORE

  2. 2. RAP1 at the Yeast Telomere

    University dissertation from Johan Wahlin, Dep. of Cell and Organism Biology, Sölvegatan 29, 223 62 Lund, Sweden

    Author : Johan Wahlin; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; DNA-binding; Saccharomyces; yeast; telomeric repeat; telomere; RAP1; repressor activator protein 1; Genetics; cytogenetics; Genetik;

    Abstract : Telomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. READ MORE

  3. 3. Importance of the Clr2 protein in heterochromatin formation in the fission yeast Schizosaccharomyces pombe

    University dissertation from Uppsala : Uppsala universitet

    Author : Daniel Steinhauf; Leif Andersson; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clr2; Yeast; Heterochromatin; Fission yeast; Schizosaccharomyces pombe; Biokemi; Biochemistry;

    Abstract : Epigenetics is an area of biology that studies heritable changes in gene ex- pression without any change in the DNA sequence. The most studied epige- netic mechanisms are DNA methylation, RNA interference and histone mod- ifications. READ MORE

  4. 4. Chromosome synapsis and recombination in yeast meiosis

    University dissertation from Stockholm : Institutionen för molekylärbiologi och funktionsgenomik

    Author : Hasanuzzaman Bhuiyan; Karin Schmekel; Harry Scherthan; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; meiosis; recombination; synapsis; yeast; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Abstract : Meiosis is a cell division process that produces haploid gametes from diploid cells. Several important meiotic events take place during prophase of meiosis I, most important being homologous chromosome pairing, meiotic recombination and formation of the synaptonemal complex (SC).

  5. 5. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    University dissertation from Stockholm : Institutionen för molekylärbiologi och funktionsgenomik

    Author : Kristofer Bodvard; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Abstract : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. READ MORE
