  1. 21. Chromatin remodeling and dna topology in transcription and genome stability

    Författare :Jenna Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Eukaryotic DNA is wrapped around histone proteins to form nucleosomes, the fundamental repeating unit of chromatin. DNA packaging into chromatin both solves and creates problems. It allows the centimeters, or even meters, of DNA that constitute a eukaryotic genome to fit inside a micrometer-scale cell nucleus. LÄS MER

  3. 22. Alpha-actinin - an amazing journey through time and species

    Författare :Barbara Addario; Lars Backman; Yari Ylänne; Umeå universitet; []
    Nyckelord :;

    Sammanfattning : In eukaryotes, the actin cytoskeleton plays an important role in a large variety of cellular events. Its reorganization is regulated by a plethora of actin-modulating proteins, such as α-actinin. α-actinin is a ubiquitous actin-binding protein that belongs to the spectrin superfamily. LÄS MER

  4. 23. Role of respiratory supercomplexes : Electronic connection between complexes III and IV

    Författare :Agnes Moe; Peter Brzezinski; James A. Letts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electron transfer; cytochrome c oxidase; cytochrome bc1; respiratory supercomplex; bioenergetics; membrane protein; biokemi; Biochemistry;

    Sammanfattning : In the final step of cellular respiration, electrons are transferred through the respiratory chain to reduce molecular oxygen to water. The energy released in this chain is used to maintain a proton electrochemical gradient across the cell membrane, which is used, for example, by the ATP synthase to produce ATP. LÄS MER

  5. 24. Genetic analysis of cell cycle and chromatin regulation in quiescent fission yeast cells

    Författare :Yasaman Zahedi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During proliferation, cells produce their genetic materials to increase the number of cells, while in the absence of nutrients or by the induction of stimulus, the proliferative phase is stopped and entry into quiescence is triggered to increase their chance of survival. Quiescence is a reversible resting phase where cells enter, in case of nutrient deprivation or damage and induced by stimuli. LÄS MER

  7. 25. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

    Författare :Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. LÄS MER
