These mutations will randomize the original sequence of the gene and it will lose its original meaning. As everyone knows, a random nucleotide strand as long as an average gene has an absurdly high number of possible sequences. A hint of this possibility comes from a 1995 study of random RNA sequences by Eckland et al. Yet they did find one such strand in a sample of that size. From similar results for other ribozymes they conclude that there are a large number of distinct RNA structures with the capability to act as ligases.
Genes apparently can tolerate a higher percentage of errors than computer code or written text.
Sixty-one codons code for only twenty amino acids, so many of the codons are synonymous. Also, proteins can tolerate amino acid substitutions at many positions without losing their function. It would make stasis in evolution difficult to explain. This situation would make the genetic code different from other codes such as computer code or written text. Perhaps the genetic code is so different, but this difference has not been demonstrated.
