Of these 64 codons, 61 represent amino acids, and three are stop signals. Although each codon is specific for only one amino acid (or one stop signal), the genetic code is described as degenerate ...

This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

should be read in translation as two alternating codons, GUG and UGU, thus encoding a protein of two alternating amino acids. Translation of the artificial GUGU mRNA yielded a protein of ...
