1. Translational termination, frameshift and ribosome assembly
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.

2. Biased Evolution : Causes and Consequences
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
3. Megencephaly, significance, biology and identification of a genetic cause
Sammanfattning : Enlarged brain is termed megencephaly or megalencephaly, and is defined as a brain volume above the 98th percentile. It is a major sign in several neurological diseases with symptoms ranging from very mild to lethal, including mental retardation, low intelligence, motoric and neurological disturbances, seizures and dysmorphic features.

4. Frameshifting as a tool in analysis of transfer RNA modification and translation
Sammanfattning : Studies of ribosomal reading frame maintenance are often based on frameshift mutation suppression experiments. In this thesis, suppression of a frameshift mutation in Salmonella enterica serovar Typhimurium by a tRNA and a ribosomal protein are described. LÄS MER
5. Translational accuracy, ribozyme efficiency and NAD metabolism in Escherichia coli
Sammanfattning : Interactions between the translational machinery and mRNA in Escherichia coli have been studied. In the first section nonsense codon readthrough and changed translational reading frame were measured in different growth phases. LÄS MER
