p-Adic Structure of the Genetic Code
Branko Dragovich
Abstract
The genetic code is connection between 64 codons, which are building blocks of the
genes, and 20 amino acids, which are building blocks of the proteins. In addition to
coding amino acids, a few codons code stop signal, which is at the end of genes, i.e.
it terminates process of protein synthesis. This article is a review of simple modelling
of the genetic code and related subjects by concept of p-adic distance. It also
contains some new results. In particular, the article presents appropriate structure of
the codon space, degeneration and possible evolution of the genetic code. p-Adic
modelling of the genetic code is viewed as the first step in further application of padic tools in the information sector of life science
