For case (iv) such effect is not expected given that the distribution of fiber-bound precursors is similar to that of the precursors in solution. ii (E AA = -2, E BB = 0, and E AB = -1, growing on A6B0 assemblies); (C) case iii (E AA = E BB = -2, and E AB = 0 growing on equal amounts of A6B0 and A0B6 fibers); and (D) case iv (E AA = E BB = 0, and E AB = -2; seeded with A3B3 fibers). Positions 1-10 in each fiber (not shown) correspond to the seed.
