    The RNA hairpin loops represent important RNA topologies with indispensable biological functions in RNA folding and tertiary interactions. Explicit solvent molecular dynamics (MD) simulation is a computational technique which can efficiently complement the experimental data and provide unique structural dynamics information on the atomic scale. Nevertheless, outcome of simulations is often compromised by imperfections in parameterization of simplified pair-wise additive empirical potentials referred also as force fields. We have pointed out in several recent studies that force field description of single stranded hairpin segments of nucleic acids may be particularly challenging for the force fields. In this paper, we report a critical assessment of a broad set of MD simulations of UUCG, GAGA, and GAAA tetraloops using various force fields.
