The 5' untranslated region (UTR) of SARS-CoV-2 genome is a conserved, functional and structured genomic region consisting of several RNA stem-loop elements. While the secondary structure of such elements has been determined experimentally, their three-dimensional structure is not known yet. Here, we predict structure and dynamics of five RNA stem-loops in the 5'-UTR of SARS-CoV-2 by extensive atomistic molecular dynamics simulations, more than 0.5ms of aggregate simulation time, in combination with enhanced sampling techniques. We compare simulations with available experimental data, describe the resulting conformational ensembles, and identify the presence of specific structural rearrengements in apical and internal loops that may be functionally relevant. Our atomic-detailed structural predictions reveal a rich dynamics in these RNA molecules, could help the experimental characterisation of these systems, and provide putative three-dimensional models for structure-based drug design studies.

Narrow Bands

In order to investigate segregation of granular binary-mixtures in a horizontally rotating cylinder, three-dimensional molecular dynamics simulations are carried out. Two kinds of particles, which have different diameters and/or different roughness of surfaces, are segregated into three bands. It is found that particles receive averaged force cohesively at the boundaries of segregated bands. The present analysis shows that segregated narrow bands are formed by diffusion process and that the cohesive forces operating at the boundaries stabilize them.
