Using various copolymers most of the remaining codons were then determined. [72] It could also reflect steric and chemical properties that had another effect on the codon during its evolution. The triplet sequence controls the amino acid sequence during protein synthesis. Each three nucleotides (triplet) in the genetic code, known as a codon, encodes a specific amino acid or stop signal. [24], Mutations that disrupt the reading frame sequence by indels (insertions or deletions) of a non-multiple of 3 nucleotide bases are known as frameshift mutations. For example, although codons GAA and GAG both specify glutamic acid (redundancy), neither specifies another amino acid (no ambiguity). 'days' : 'day' }} The bases survived cell division. Optimality: the genetic code continued to evolve after its initial creation, so that the current code maximizes some, Chemical principles govern specific RNA interaction with amino acids.
