本文介绍了用8×8表对密码子空间(核苷酸三元组)进行参数化的简单方法。这个表(我们称之为二进平面)具有自然的2-adic超度量。我们表明,这种参数化后的遗传密码将是一个简单的形式的局部常数映射。该图的局部恒定性将描述遗传密码的简并性。遗传密码图谱定义了氨基酸空间上的2-adic超度量。我们表明,疏水性氨基酸将聚集在两个球相对于这个超度量。因此,密码子空间的参数化展示了遗传密码的隐藏规律。
We introduce the simple parametrization for the space of codons (triples of nucleotides) by 8×8 table. This table (which we call the diadic plane) possesses the natural 2-adic ultrametric. We show that after this parametrization the genetic code will be a locally constant map of the simple form. The local constancy of this map will describe degeneracy of the genetic code. The map of the genetic code defines 2-adic ultrametric on the space of amino acids. We show that hydrophobic amino acids will be clustered in two balls with respect to this ultrametric. Therefore the introduced parametrization of space of codons exhibits the hidden regularity of the genetic code.
