1. Characterisation of starch: development of analytical methods
Sammanfattning : Starch, comprised of amylose and amylopectin, is a very complex biopolymer. Different methods are therefore needed for the investigation of the molecular structures of amylose and amylopectin. In this thesis analytical methods have been developed and various techniques were combined for the characterisation of starch. LÄS MER
2. Microstructure and enzymatic stability of ethyl-o-(hydroxyethyl)- cellulose
Sammanfattning : .... LÄS MER
3. The Effects of Mutation and Selection on the Rate and Pattern of Molecular Evolution in Birds
Sammanfattning : By comparing sequence diversity and divergence on sex chromosomes one can study how the rate of evolution in affected by mutation and/or selection. The rate of mutation in male biased, meaning that relatively more mutations are created in the male germ line than in the female. LÄS MER
4. Comparative Genomics in Birds
Sammanfattning : To shed light on forces that shape the molecular evolution of bird genomes, and in turn avian adaptations, comparative analyses of avian DNA sequences are important. Moreover, contrasting findings in birds to those of other organisms will lend a clearer view on general aspects of molecular evolution. LÄS MER
5. Birds as a Model for Comparative Genomic Studies
Sammanfattning : Comparative genomics provides a tool to investigate large biological datasets, i.e. genomic datasets. In my thesis I focused on inferring patterns of selection in coding and non-coding regions of avian genomes. LÄS MER
