  1. 21. Control of Chromosome and Plasmid Replication in Escherichia coli

    Författare :Jan Olsson; Kurt Nordström; Santanu Dasgupta; Måns Ehrenberg; Anders Lobner-Olesen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Life is cellular. Cells grow and divide to give two new cells; this process is called the cell cycle. The chromosome in a bacterium is replicated into two identical copies before the cell divides. DNA replication is a fundamental process common to all forms of life. LÄS MER

  3. 22. Protein interactions involved in viral replication characterized by T7 phage display

    Författare :Hamid Houshmand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; protein-protein interaktion; fagdisplayteknik; HCV; polyomavirus; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Protein interactions are essential for many cellular processes. By utilizing protein-protein interactions, viruses can infect their host cells and replicate. Phage display can be used for identification and characterization of protein-protein interactions. LÄS MER

  4. 23. Mammalian cell cycle regulation : characterisation of three genes expressed in proliferating cells

    Författare :Maria Starborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cell cycle; DNA replication; licensing factor; mitosis; ceheckpoint regulator; centromere regions; cell proliferation marker; nucleolar protein; spermatogenesis;

    Sammanfattning : Proliferating cells undergo different phases in their life cycle. During interphase the cells grow and duplicate their DNA content, followed by a cell division phase, mitosis, which results in two daughter cells. LÄS MER

  5. 24. Regulation of the bacterial cell cycle in response to starvation

    Författare :David J. Leslie; Kristina Jonas; Sean Crosson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Bacteria have adapted to diverse environments, which are often unpredictable and constantly changing. In order to survive, bacteria need to make the most of nutrients while they are available, while being prepared to rapidly change their behaviour when conditions take a turn for the worse. LÄS MER

  7. 25. Cell cycle analysis of archaea

    Författare :Andrzej Poplawski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : In my thesis, the cell cycle analysis of archaea and hyperthermophilic organisms is presented for the first time. Crenarchaea from the genus Sulfolobus were used as a model system. Plow cytometry and light microscopy were applied to investigate the timing and coordination of different cell cycle events. LÄS MER
