This is a well-established fact about genetic code is that code is universal and consists of codons set in the customary typical tabulation that on the other hand go around as greatly non-random. Various communally allied theories were specified concerning the perceptions about the origin and evolution of the genetic code. There are not many accomplishments in the short past account of molecular biology which had an intense impact on the progression of science and at the same time are stalwartly embossed in the civic insight. Decoding and interpretation of Genetic code is definitely one of such event. The genetic code is vital to each and every form of existence and is of elementary significance to the entire biology. Earlier it was a conviction that protein is accountable for transferring the genetic information from one to the other generation. All concepts and theories in nutshell recommended that the customary code might have no unique features but was preset simply because each and every existing forms of life have a common predecessor, by way of consequent alterations to the code, irrelevant of the lethal effects of codon relocations. A genuine and factual appreciation of the origin and evolution of this genetic code can be accomplished only in juxtaposition with a plausible setting for the evolution of the theories of coding and translation coordination. Here the discourse of the perceptions of various workers and evolution of the genetic code with time is discussed.
