Abstract:Low complexity repeat RNA sequences self-associate by homotypic interactions to form condensates. Using simulations of a coarse grained Single-Interaction Site model for (CAG)n(n= 30 and 31), we show that the salt-dependent free energy gap, ∆GS, between the ground (perfect hairpin) and the excited state (slipped hairpin (SH) with one CAG overhang) of monomer (neven) is the primary factor that determines the rates and yield of self-assembly. For oddn, the SH ground state free energy (GS) is used to predict self… Show more
