We study numerically the binding of one semiflexible charged polymer onto an oppositely charged sphere. Using parameters appropriate for DNA-histone complexes, we find complete wrapping for intermediate salt concentrations only, in agreement with experiments. For high salt concentrations, a strongly discontinuous dewrapping occurs. For low salt concentrations, we find multiple conformational transitions, leading to an extended DNA configuration. The wrapped states are characterized by… CONTINUE READING
