For instance, if we examine leucine, leucine contains six different codons, unique codons that essentially encode for that specific leucine amino acid. And this means all these different codons. So we have 123456 so UA ugcu cu, g CUC and cua. All these six different codons will create the same exact amino acid, namely leucine. And these different codons that encode for the same exact amino acid are known as synonyms. Now, what's the big deal about this idea that the genetic code is degenerative?
