Certain inhibitors of nucleic acid and protein synthesis, namely actinomycin D, mitomycin C, and puromycin, have been found to block the expression of a persistent daily rhythm of bioluminescence. The action does not inhibit luminescence per se but rather the rhythmicity. Exposure of the cells to these inhibitors for only a few hours, which might be expected to thereby delay the rhythm by a few hours, does not in fact have this effect. Chloramphenicol and amethopterin do not inhibit the rhythm. It is proposed that the functioning of the clock-like rhythmic mechanism depends upon the cell's normal ability to synthesize RNA.
