Method By using DNA microarrays, researchers precisely measured the decay of each yeast mRNA, after thermal inactivation of a temperature-sensitive RNA polymerase II.
Comments The half-lives of the 4,687 mRNAs analyzed varied widely, ranging from ~3 min to more than 90 min, with a mean of 23 min and median of 20 min. The ribosomal proteins are encoded by 137 different mRNAs (there are 59 duplicated genes) (ref 31). The 131 ribosomal protein mRNAs analyzed in this study had remarkably similar half-lives, with t1/2=22±6min
