    Protein-DNA interactions are indispensable players in the daily activities of cells. DNA-binding proteins regulate gene expression and are responsible of DNA replication, packaging, repair and recombination. Among them, ...

    On the development of computational tools for the study of protein-protein interactions and protein-protein binding 

    Marín López, Manuel Alejandro (Date of defense: 2017-01-13)

    Proteins are involved in almost all cell processes, with physical interaction between them being key to their function and dictated by its 3D structure. Hence, the study of protein-protein interactions and protein-protein ...

    On the evolution of cancer genomes : Signatures of selection reveal cancer genes across multiple tumor types 

    Zapata Ortiz, Luis (Date of defense: 2016-10-05)

    Tumors are composed of fast-growing cells that become malignant under selection of biological functions needed for cancer development. In this thesis, I intend to uncover the basic evolutionary principles underlying cancer ...

    On the flexibility of the perception and cognition of broken harmonic expectations 

    Pagès-Portabella, Carlota (Date of defense: 2023-10-19)

    La música està present en totes les cultures. Tot i tenir les mateixes habilitats auditives, la manera en la què experimentem la música depèn del context cultural, la música que escoltem en el dia a dia o si hem rebut ...

    On the orchestration of dorsal closure in Drosophila melanogaster : from tissue-scale control to cellular-scale remodeling 

    Hayes, D. Peran (Date of defense: 2016-12-13)

    The vast diversity of life on Earth develops from relatively uniform beginnings via self-organised movements occurring between groups of cells. Whilst the variety of shapes resulting from morphogenesis is boundless, the ...

    On the prevalence and role of epistasis in shaping fitness within and between populations 

    Söylemez, Onuralp (Date of defense: 2015-10-09)

    The role of epistasis – inter-dependent contributions of alleles to fitness – in shaping genetic variation within and between populations is an important question in evolutionary biology with significant implications for ...
