Numerical Equality within Codon and Amino Acid Pool Beyond Bilateral Polar & Non Polar Amino Acid Partitioning

The Author had previously arrived at the numerical equality between 10 canonical polar amino acids (AA) & 10 canonical non polar AA in terms of binary representation of their codon as well as anticodon bases out of 24 available configurations and thereby had frozen the binary representation of the corresponding nucleotide bases [1] to specific configurations, one pair for L- amino acids codons and anticodons and another pair for D- amino acid codons and anticodons. In contrast, no numerical equality was observed between 10 canonical AA linked to aaRS-I (aminoacyl t-RNA synthetases-I) enzymes and the rest 10 canonical AA linked to aaRS-II enzymes in any of the 24 configurations. Present research article is about the search for such equality and consequence thereof if any equality is observed at all.Fortunately, numerical equality is discovered by suitable minor tweaking of aaRS affiliation of AA and it leads to several dramatic inferences. One, it extends the symmetry feature from DNA, mRNA and transfer-RNA (tRNA) anticodon level to the larger domain of aaRS enzymes. Two, it points out to the possibility of AA Tyrosine being correlated to some features of an aaRS-II enzyme (or its distant ancestors) despite being linked to an aaRS-I enzyme. In the same breadth, it points out to the possibility of AA Lysine being correlated to an aaRS-I enzyme (or its distant ancestors) despite being linked to an aaRS-II enzyme. Third, it hints at aaRS for the amino acid Asparagine(N) being fully operational only after Lys-aaRS-I gave way to Lys-aaRS-II. Interestingly, though the above inferences are derived theoretically, they conform to several experimental evidences in an indirect manner.
