Statistics associated with the calculated half-lives of 2856 genes in the rph-1 control strain and the two RNase mutants. Two different models were tested: the model without delay corresponding to classical linear model fitted on log concentration of mRNA a and the model with delay previously described [35] corresponding to a piecewise model composed of a stable baseline level during the delay followed by an exponential decay b. Results for each strain are represented as boxplots and the related statistics are described below in numbers
