tailieunhanh - The influence of different types of translational inaccuracies on the genetic code structure

The standard genetic code is a recipe for assigning unambiguously 21 labels, . amino acids and stop translation signal, to 64 codons. However, at early stages of the translational machinery development, the codons did not have to be read unambiguously and the early genetic codes could have contained some ambiguous assignments of codons to amino acids. |
