Fig. 1.

Predicted and observed relationships in gene expression in the BY4741 yeast strain. (A) Illustration of the classical totally asymmetric exclusion process (TASEP) with constant rates of initiation, elongation, and termination. (B) Relationship between protein abundance (ref. 18) and the density of RPFs on the ORF, or the mRNA abundance. (C) Relationship between the number of RPFs mapped to individual mRNAs and the corresponding ORF length, mRNA level, and both. p and s are Pearson’s and Spearman’s correlation coefficients, respectively.
