Abstract

Investigation of mRNA sequence organization is of importance to reveal the features influencing translation efficiency and specificity. We performed statistical analysis of translation initiation and termination sites of well-studied eukaryotic organism Saccharomyces cerevisiae. Yeast mRNAs were analyzed using trinucleotide weight matrices and vocabularies of significant oligonucleotide motifs. A statistically significant difference of nucleotide contexts between high- and low-expressed mRNAs was found. Computer simulation of evolution using genetic algorithm demonstrated that the rate-limiting stage model could explain this phenomenon.
