We have measured the decay half-life of functional messenger RNA (mRNA) for some thirty different proteins in the yeast Saccharomyces cerevisiae. Production of newly synthesized mRNA was halted by raising the temperature of a culture of a temperature-sensitive mutant, ts 136. Aliquots of this culture were pulsed-labelled with [35S]-methionine at various times after the temperature shift and the radioactive proteins separated on the two-dimensional gel electrophoresis system of O'Farrell. We find a range in the decay half lives of individual mRNA species which varies from 3.5 min to greater than 70 min. We find three general classes of decay curves, (a) simple exponential (first order); some of these showed a shoulder before onset of exponential decay; (b) bi-component or multi-component concave upward; (c) initial stimulation of rate of mRNA synthesis, followed by virtually undetectable decay.
