  1. 1. Catabolism of Pyrimidines in Yeast

    Författare :Anna Rasmussen; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

    Sammanfattning : 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. LÄS MER

  3. 2. RAP1 at the Yeast Telomere

    Författare :Johan Wahlin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; DNA-binding; Saccharomyces; yeast; telomeric repeat; telomere; RAP1; repressor activator protein 1; Genetics; cytogenetics; Genetik;

    Sammanfattning : 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. LÄS MER

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

    Författare :Daniel Steinhauf; Leif Andersson; Uppsala universitet; []
    Nyckelord :Clr2; Yeast; Heterochromatin; Fission yeast; Schizosaccharomyces pombe; Biokemi; Biochemistry;

    Sammanfattning : 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. LÄS MER

  5. 4. Chromosome synapsis and recombination in yeast meiosis

    Författare :Hasanuzzaman Bhuiyan; Karin Schmekel; Harry Scherthan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meiosis; recombination; synapsis; yeast; Molecular biology; Molekylärbiologi;

    Sammanfattning : 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).

  7. 5. The Genetics of Adaptation and Evolvability in Yeast

    Författare :Karl Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Genetics; Adaptation; Evolvability; Yeast;

    Sammanfattning : Evolution is the hereditary change in life forms that has shaped the divergence of all organisms that inhabit planet Earth. I used the yeast Saccharomyces cerevisiae to study how adaptive evolution increases the fitness and changes the properties of experimental and natural yeast populations. LÄS MER
