- The codon models constitute a special case of independent tuple models where sequence states that correspond to stop codons are excluded from the state space. For example, a codon model for the standard genetic code has 61 states corresponding to the sense codons, 3 states less than the full trinucleotide state space of 64.
Examples
-
In molecular biology, researchers study the function of a trinucleotide as a coding unit within RNA.
-
We present the NF and TF models for dinucleotides, but note that essentially the same treatment applies to trinucleotides and larger units.

Morphology
trinucleotide = nucleotide (transparent) = tri + nucleotide
Formed by the productive prefix 'tri-' (three) applied to the established biomedical term 'nucleotide', yielding the literal meaning 'three nucleotides'.
Etymology
Trinucleotide comes from tri- meaning 'three', as in triangle or tricycle, and nucleotide meaning a small 'unit' of DNA or RNA. So a trinucleotide is a group of three such units that often 'codes' for one amino acid.
