遗传密码的水晶基地

A crystal base for the genetic code

L. Frappat, A. Sciarrino, P. Sorba

摘要:

提出了量子包络代数U_q(sl(2)\oplus sl(2))在极限q \to 0中作为遗传密码的对称代数.在这种方法中,DNA链中的核苷酸或密码子的三联体被分类为晶体碱基,U_{q \to 0}(sl(2)\oplus sl(2))表示的张量积。这种结构可以与基本粒子物理学中的夸克积木重子分类相比较,这是晶体基础性质的主要区别之一,提供了状态成分的自然顺序,这种顺序在密码子中至关重要。然后,确保对应密码子/氨基酸的运算符可以从上述代数中构造出来。它将被称为阅读操作符,并且是这样的,即两个密码子相对于同一个(分别为:不同的)氨基酸获得相同的(相应地,不同的)特征值。

英文摘要:

The quantum enveloping algebra U_q(sl(2) \oplus sl(2)) in the limit q \to 0 is proposed as a symmetry algebra for the genetic code. In this approach the triplets of nucleotids or codons in the DNA chain are classified in crystal bases, tensor product of U_{q \to 0}(sl(2) \oplus sl(2)) representations. Such a construction might be compared to the baryon classification from quark building blocks in elementary particles physics, one of the main differences standing in the property of a crystal base to provide a natural order in the state constituents, this order being crucial in the codon. Then an operator ensuring the correspondence codon/amino-acid can be constructed out of the above algebra. It will be called the reading operator, and be such that two codons relative to the same (resp. different) amino-acid(s) acquire the same (resp. different) eigenvalue(s).
