RNA, or ribonucleic acid, plays an essential role in many biological processes, not only as messenger molecule with the task of transmitting genetic information from the nucleus to the cytoplasm for protein production, but also as protagonist of different and significantly important cellular mechanisms. In many of these, its structure plays a crucial role. Structure is different and characteristic for each RNA depending on the sequence of specific units, known as nucleotides. A research team at SISSA, led by Professor Giovanni Bussi, has developed a computerised simulation model that effectively predicts the three-dimensional conformation of the RNA filament starting from a sequence of nucleotides. The lead author of the study, just published in the journal Nucleic Acids Research, is SISSA researcher Simón Poblete. The work promises to have a significant impact in the research and application field.
