16. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State
Sammanfattning : 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.

17. Variation in length of proteins by repeats and disorder regions
Sammanfattning : Protein-coding genes evolve together with their genome and acquire changes, some of which affect the length of their protein products. This explains why equivalent proteins from different species can exhibit length differences. LÄS MER
18. Transcription Associated Recombination in Mammalian Cells
Sammanfattning : There is increasing evidence that the movement of the transcription machinery through DNA has profound effects on the genomic stability. One such example is a phenomenon known as Transcription Associated Recombination (TAR). Transcription enhances recombination levels to a high degree in all organisms studied, from bacteria to mammals. LÄS MER
19. Involvement of Homologous Recombination in Response to Different Qualities of DNA Damage
Sammanfattning : The present studies aimed at elucidate the role of homologous recombination (HR) for the repair of different qualities of DNA damages and/or changes in chromatin structure induced by a variety of radiation qualities.Radiation qualities used to expose cells in culture ranged from non-ionizing radiation with extremely low frequency (ELF), of energies too low to disrupt chemical or molecular bonds, to radiation qualities with energies able to induce ionizations and break chemical bonds.

20. Identification of novel BRCA2-binding proteins that are essential for meiotic homologous recombination
Sammanfattning : Meiotic recombination is a molecular process in which the induction and repair of programmed DNA double-strand breaks (DSBs) creates genetic exchange between homologous chromosomes and thus increases genetic diversity and ensures chromosome segregation. Breast cancer susceptibility gene 2 (BRCA2) is a potent cancer suppressor and is required for DSB repair by homologous recombination (HR) in mitosis. LÄS MER
