If by deterministic you mean informationally, that is with complete information we have the possibility to predict any future states (barred complexity), then we most definitely know that molecular interactions are not deterministic. However, even hypothesizing a deterministic universe, you could have different starting conditions that would evolve to different universes, and while you are at it, why not postulates different deterministic laws?
