dc.description.abstract The human genome sequence can be thought of as an instruction manual for our species, written and rewritten over more than a billion of years of evolution. Taking a complete inventory of our genome, dissecting its genes and their functional components, and elucidating how these genes are selectively used to establish and maintain cell types with markedly different behaviors, are key challenges of modern biology. In this thesis we present contributions to our understanding of the structure, function and evolution of the human genome. We rely on two complementary approaches. First, we study signatures of evolutionary processes that have acted on the genome using comparative sequence analysis. We generate high quality draft genome sequences of the chimpanzee, the dog and the opossum. These species share a last common ancestor with humans approximately 6 million, 80 million and 140 million years ago, respectively, and therefore provide distinct perspectives on our evolutionary history. We apply computational methods to explore the functional organization of the genome and to identify genes that contribute to shared and species-specific traits. Second, we study how the genome is bound by proteins and packaged into chromatin in distinct cell types. We develop new methods to map protein-DNA interactions and DNA methylation using single-molecule based sequencing technology. We apply these methods to identify new functional sequence elements based on characteristic chromatin signatures, and to explore the relationship between DNA sequence, chromatin and cellular state. en_US
