摘要翻译：
对92种生物在整个外显子区的四位密码子的使用频率进行了分析。第三核苷酸A和C的同义密码子的使用频率与属于四位体适当子集的第三核苷酸相同的非同义密码子的使用频率之间存在相关性。指出了属于密码子四组编码集合子集的氨基酸之间的相关性。指出计算出的四元组Shannon熵对生物物种的依赖性很弱。观察到的相关性很好地符合遗传密码晶体基模型的数学方案。

英文摘要：
The usage frequencies for codons belonging to quartets are analized, over the whole exonic region, for 92 biological species. Correlation is put into evidence, between the usage frequencies of synonymous codons with third nucleotide A and C and between the usage frequencies of non synonymous codons, belonging to suitable subsets of the quartets, with the same third nucleotide. A correlation is pointed out between amino acids belonging to subsets of the set encoded by quartets of codons. It is remarked that the computed Shannon entropy for quartets is weakly dependent on the biological species. The observed correlations well fit in the mathematical scheme of the crystal basis model of the genetic code.
