Introduction

Unifying various approaches to the genetic code

1. Geometric approach to the genetic code

2. 4-adicity and 5-adicity as possible realizations of the symmetries of the genetic code

3. Number theoretical thermodynamics and genetic code

4. Divisor code

5. Group theoretic interpretation of the divisor code

6. Topological interpretation of the divisor code in TGD framework

7. Is the fusion of geometric, thermodynamical, and divisor code approaches possible in the 5-adic case?

5-adicity or 4-adicity?

1. The problems of the 4-adic model of the divisor code

2. 5-adic model works for thermodynamics based on partitions

5-adic thermodynamical model for the genetic code

1. The simplest model for the 5-adic temperature

2. The simplest possible model for thermodynamics

3. Number theoretic Hamilton depending on the number of partitions of integer characterizing DNA

4. Number theoretical Hamiltonian identified as spin-spin interaction

A possible physical interpretation of various codes in TGD framework

1. Generalization of imbedding space and interpretation of discrete bundle like structures

2. A possible interpretation for the divisor code

3. About the geometric interpretation for the thermodynamics of partitions of n₂₎

4. About the physical interpretation for the thermodynamics of partitions of n₂₎

5. A possible interpretation for the p-adic prime labelling aminoacid and DNAs coding it

Appendix: 4-adic realization of n→ n+32 symmetry, divisor code, and labelling of aminoacids by primes are not mutually consistent
