The genetic code as a periodic table: algebraic aspects.
The systematics of indices of physico-chemical properties of codons and amino acids across the genetic code are examined. Using a simple numerical labelling scheme for nucleic acid bases, A=(-1,0), C=(0,-1), G=(0,1), U=(1,0), data can be fitted as low order polynomials of the six coordinates in the 64-dimensional codon weight space. The work confirms and extends the recent studies by Siemion et...
متن کاملA New Genetic Code Table
In this paper it is shown that within a Combined Genetic Code Table, realized through a combination of Watson-Crick Table and Codon Path Cube it exists, without an exception, a strict distinction between two classes of enzymes aminoacyl-tRNA synthetases, corresponding two classes of amino acids and belonging codons. By this, the distinction itself is followed by a strict balance of atom number ...
متن کاملSome Algebraic Aspects of Morse Code Sequences
1 Morse code polynomials Morse code sequences are finite sequences of dots (•) and dashes (−). If a dot has length 1 and a dash has length 2 then the number of all such sequences of total length n−1 is the Fibonacci number Fn, which is defined as the sequence of numbers satisfying the recursion Fn = Fn−1 + Fn−2 with initial conditions F0 = 0 and F1 = 1. If a dash is assumed to have length j, j≥...
متن کاملAlgebraic Evolution of the Genetic Code
The evolution of the genetic code has been speculated by many authors, but all of them lack determinative proofs. Jukes [4] inferred the evolution from mitochondrial codes, which are different from the universal codes in some respects. He postulated an archetypal code containing 14 amino acids, from which the universal code could evolve by gene duplication followed by mutational changes. This p...
متن کاملAlgebraic Matching of Vulnerabilities in a Low-Level Code
This paper explores the algebraic matching approach for detection of vulnerabilities in binary codes. The algebraic programming system is used for implementing this method. It is anticipated that models of vulnerabilities and programs to be verified are presented as behavior algebra and action language specifications. The methods of algebraic matching are based on rewriting rules and techniques...
