Quizplus · Accepted Answer

Codons are sequences of three nucleotides in DNA or RNA that specify which amino acid will be added next during protein synthesis. They are not the basic units of protein structure (that would be amino acids themselves), and while a single amino acid can be coded by more than one codon due to the redundancy of the genetic code, a single codon does not code for more than one amino acid.
