Comments P.10 left column top paragraph: "The median lengths of 5'/3'-untranslated regions revealed by tiling array hybridization [ref 26] and RNA-Seq [ref 27] were reported to be 68 nt/91 nt and 50 nt/104 nt, respectively. Thus, the average length of mRNA is 1,500 nt, coincident with the previous estimate [ref 19]. However, it should be noted that a significant negative correlation was observed between expression level and ORF length in the budding yeast [ref 28]. Indeed, the average size of the yeast ORFs can be as short as 1,123 nt and 1,083 nt when weighted by the copy numbers calculated from signal intensity of high-density DNA microarray [ref 29] and GATC-PCR results, respectively. Thus, the average length of mRNA should be regarded as ~1,250 nt rather than 1,500 nt."
