Correlation of core promoter type with protein translation features. A. The median, 25% and 75% quartiles lengths of the 5' UTR in each gene set. B. The median, 25% and 75% quartiles lengths of the 3' UTR in each gene set. C. The percentage of genes with the Kozak translation initiation context in each of the indicated gene set. D. The p-values of the differences in the median values (A&B) and Kozak probability (C) were calculated using the Kruskal-Wallis test with Bonferroni correction and chi-square distribution respectively. NS is a non-significant difference (p > 0.05).
