PhD position: Designing modified DNA fragments

Doctoral study program: Life Sciences (Faculty of Science, Masaryk University)

Research area: Structural Biology

Supervisor: Radek Marek

Annotation

Novel forms of nucleotides will be incorporated in silico in oligomers with sequences relevant for biosystems. The biocompatibility of artificial building blocks will be evaluated using advanced methods of quantum chemistry (that provide also analytical tools for investigation of crucial noncovalent interactions) and molecular dynamics. Available candidates of modified nucleobases and sugars will be investigated experimentally by using NMR spectroscopy in solution.
