a specific sequence of three adjacent nucleotides on a strand of DNA or RNA that specifies the genetic code information for synthesizing a particular amino acid
"During their biology lab, the students analyzed how each codon in the mRNA sequence directs the ribosome to assemble the correct chain of amino acids."
A handbell used for summoning monks.
"The genetic mutation altered a single codon, causing the ribosome to insert the wrong amino acid and halt protein production early."
A sequence of three adjacent nucleotides, which encode for a specific amino acid during protein synthesis or translation.
