Final Report Abstract
The current project has been focused on understanding of nucleic acid packing inside virus capsids and kinetics of virus self‐assembly. The major focus was on (i) implications of intermolecular interactions between the DNA under confinement, (ii) the adsorption and charge matching of flexible RNA chains during virus self‐assembly, (iii) the effects of macromolecular crowding in the cell cytoplasm on the reaction kinetics and diffusion of various molecular components. A significant progress was achieved in each of these key directions, as recognized by the publication record in solid scientific journals and the overall PI’s output.
