Welcome to the Jemielity Group

Welcome at the website of Jacek Jemielity Group at Centre of New Technologies and the Division of Biophysics, Faculty of Physics, University of Warsaw. Our group is interested in the chemical synthesis, properties and applications of modified nucleotides and nucleic acids. Our research encompasses improving methods for the chemical synthesis of nucleotide analogs, designing new modified nucleotides as tools for molecular biology and conjugating nucleotides to labels, tags and new materials. One of our particular interests, is development of eukaryotic mRNA cap analogs with potential medicinal applications.
