  1. (A) Spearman’s and Kendall’s correlation coefficients to assess an association between the presence/absence of hexanucleotide sequences corresponding to the inhibitory codon pairs in 3’ UTR regions. The UTR annotations are based on a study by Snyder and colleagues [17]. P values obtained according to Kim [16] and those based on permutation tests are shown. (B) Same as (A) but for UTR annotations based on a study by Steinmetz and colleagues [18]
