Zinc stimulates cytochrome c synthesis in Ustilago sphaerogena under conditions where the net rates of synthesis of protein, DNA, and RNA are unaffected. We find that zinc 65 enters the cell as a first-order process within 1 min, that the incorporation of leucine-14C into cytochrome c is increased within 6 min, and that small but repeatable differences in RNA profiles are detectable within 15 min.
