  1. 1. Probabilistic Modelling of Domain and Gene Evolution

    Författare :Sayyed Auwn Muhammad; Jens Lagergren; Bastien Boussau; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Phylogenomics; Evolution; Domain Evolution; Gene tree; Domain tree; Bayesian Inference; Markov Chain Monte Carlo; Homology Inference; Gene families; C2H2 Zinc-Finger; Reelin Protein; Computer Science; Datalogi;

    Sammanfattning : Phylogenetic inference relies heavily on statistical models that have been extended and refined over the past years into complex hierarchical models to capture the intricacies of evolutionary processes. The wealth of information in the form of fully sequenced genomes has led to the development of methods that are used to reconstruct the gene and species evolutionary histories in greater and more accurate detail.

  3. 2. Bioinformatics, evolution and revolution in our understanding of toxin-antitoxin systems

    Sammanfattning : Bacteria experience a wide range of natural challenges during their life cycles, to which they must respond and adapt to live. Under stressed conditions such as amino acid starvation, bacteria slow down their growth mechanism by producing small alarmone nucleotides guanosine pentaphosphate (pppGpp) and tetraphosphate (ppGpp), collectively referred to as (p)ppGpp. LÄS MER

  4. 3. Impact of Geographical and Environmental Structures on Habitat Choice, Metapopulation Dynamics and Genetic Structure for Hazel Grouse (Bonasa bonasia)

    Författare :Jonas Sahlsten; Jacob Höglund; Eric Rapaport; Markku Pyykönen; Jon Swenson; Uppsala universitet; []
    Nyckelord :Ecology; Landscape; Patch occupancy model; Perimeter-area ratio; Geneland; Dispersal; Neighbourhood size; Ekologi;

    Sammanfattning : In this work suitable habitats for hazel grouse (Bonasa bonasia) were identified using ecological niche factor analysis (ENFA). The results from ENFA reveal that hazel grouse utilize a different and more restricted niche than what is generally available in the study area. LÄS MER

  5. 4. Translational termination, frameshift and ribosome assembly

    Författare :Monica Rydén Aulin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of this thesis was to study components involved in translational termination. Most of the work is centered around this, but the outcome of some of the experiments, led me onto other paths too.Firstly, isolation of a mutant which was shown to be in release factor one, was mapped to min 26,5 on the Escherichia coli chromosome.
