The Triplet Genetic Code - Assignment Example The commonly used theory is the Stereochemical Theory that states that codon tasks are influenced by the physiochemical similarities amongst anticodons (cognate codons) and amino acids. The second theory is the Coevolution Theory that asserts that amino acids biosynthesis conduits and the code structure coevolved. The third is the "error minimization theory" that posits that the selectiveness to reduce the negative effects of point mutations and errors of translation comprised a big part of the evolution of the code. The similarities between amino acids and cognate triplets seen in "Aptamer Selection Experiments" seem exclusive in relation to enhanced tasks of the involved amino acid in the standardized code table (Caporaso, Yarus & Knight, 2005). Therefore, regardless of whether these affinities are related to the code's origin, the properties in relation to "error minimization" with regard to the standardized code continue to prompt added elucidations. Stereochemical Theory supporters contend that some assignments of the amino acids have stereochemical qualities, while others have transformed into discriminatory compulsion for error minimization, leading to the seen sturdiness of the standardized code. Biological experiments have indicated that even when about 8-12 amino acids tasks are fixed within the standardized table, there remain many spaces to generate highly optimized genetic codes (Pain, 2010). The explanation aforementioned, however, is seen to contradict with a number of biological proof.
