Abstract: We prove that if a mixing map $ f:[0,1] \to [0,1]$ belongs to the $ {C^0}$-closure of the set of iterates and $ f(0) \ne 0$, $ f(1) \ne 1$ then $ f$ is an iterate itself. Together with some one-dimensional techniques it implies that the set of all iterates is nowhere dense in $ C([0,1],[0,1])$ giving the final answer to the question of A. Bruckner, P. Humke and M. Laczkovich.
