  1. 11. Molecular Cloning and Functional Characterization of Factors Involved in Post-transcriptional Gene Expression

    Författare :Shao-Bo Jin; Lars Wieslander; Maria Carmo-Fonseca; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene expression; pre-mRNA processing; pre-rRNA processing; Molecular biology; Molekylärbiologi;

    Sammanfattning : Gene expression in the eukaryotic cell is a fundamental cellular process, which consists of several distinct steps but extensively coupled to each other. From site of transcription in the nucleus to the cytoplasm, both mRNA and rRNA are associated with a proper set of proteins. LÄS MER

  3. 12. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs

    Författare :Erik Holmqvist; E. Gerhart H. Wagner; Udo Bläsi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small RNA; sRNA; non-coding RNA; antisense; gene regulation; post-transcriptional regulation; translational control; outer membrane protein; OmpA; MicA; biofilm; flagella; curli; bistability; Lrp; MicF; CsgD; FlgM; OmrA; OmrB; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. LÄS MER

  5. 14. Genetics and Growth Regulation in Salmonella enterica

    Författare :Jessica M. Bergman; Diarmaid Hughes; Dan I. Andersson; Måns Ehrenberg; Stanley Maloy; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tufA; tufB; EF-Tu; ppGpp; Stringent response; RNase E; RNA turnover; Post-transcriptional regulation; rpoB; rpoS; Growth in stationary phase; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Mikrobiologi; Microbiology; Molekylär genetik; Molecular Genetics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. LÄS MER

  7. 15. Biased Evolution : Causes and Consequences

    Författare :Gerrit Brandis; Diarmaid Hughes; Erik Böttger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Codon usage bias; Post-transcriptional regulation; Recombination; Inversion; EF-Tu; Frameshift suppression; Antibiotic resistance; Rifampicin; Ciprofloxacin; Compensatory evolution; Drug efflux; RNA polymerase; DNA gyrase; Mikrobiologi; Microbiology;

    Sammanfattning : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. LÄS MER
