tRNA anticodon sequences bind to mRNA codon sequences during translation to help specify the sequence of amino acids in a protein.

Some tRNAs can recognize more than one codon sequence due to the "wobble" phenomenon, which allows for flexibility in the genetic code.

Each codon on the mRNA molecule can specify multiple amino acids, therefore fewer codons are present than the total number of amino acids in a cell.

There are 64 possible codons, but only 20 amino acids are commonly used to build proteins.
