The structure of GCN4 mRNA considered in the stochastic model. Numbers indicate the positions of start codon of the uORFs, start and end of GCN4, and the end of the mRNA. Histidine codons in GCN4 are highlighted (* CAU, # CAC). The mRNA is cut into two sections, namely the 5'-(1~555 nt) and the 3'-(556~1534 nt) fractions.
