  2. 1. Experimental Evolution : and Fitness Effects of Mutations

    Author : Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Abstract : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. READ MORE

  4. 2. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Abstract : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. READ MORE

  5. 3. Translational termination, frameshift and ribosome assembly

    Author : Monica Rydén Aulin; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.
