Before revision: We study unzipping of a complementary RNA-DNA helix applied to an external force . The force-force correlations are measured, and compared to predictions from an exact solution of a 1-d toy model , as well as field theory based on functional renormalization.
After revision: We study unzipping of a complementary RNA-DNA helix applied to an external force , focusing on the force-force correlations are measured, and compared to predictions from an exact solution of a 1-d toy model , as well as field theory based on functional renormalization.
