The Codon Adaptation Index (CAI) is a measure used to evaluate the relative adaptation of a gene's codon usage to that of a reference organism or a set of highly expressed genes. It provides an assessment of how well the codons used in a particular gene match the codon preferences of an organism, which can influence the efficiency of protein expression.
