1. Bacterial DNA repair and molecular search
Abstract : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. READ MORE

2. DNA in centromeres of Chironomus pallidivittatus
Abstract : The centromeres of most higher eukaryotes are embedded within large regions of constitutive heterochromatin and consist of large quantities of highly repetitive DNA. Transposable elements are also found in these regions. READ MORE

3. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation
Abstract : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. READ MORE

4. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State
Abstract : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.

5. Mechanisms and DNA Specificity in Site-specific Recombination of Integron Cassettes
Abstract : Bacterial resistance to antibiotics has become a serious problem. This is due to the remarkable ability of bacteria to respond and rapidly adapt to environmental changes. Integrons are elements with the capacity for gene capture by an integron-encoded site-specific recombinase called IntI. READ MORE
