In a phenomenon called codon bias, some codons for a particular amino acid are used more frequently (sometimes much more frequently) than others. A minimum of 32 tRNAs are required to translate all 61 codons (31 to encode the amino acids and 1 for initiation) due to wobble positioning

Multiple tRNAs representing the same amino acid are called isoaccepting tRNAs; because they are all recognized by the same synthetase, they are also described as its cognate tRNAs.
