Examples

  • Along these lines, for the case of intron sequence evolution, the authors consider the most general time-reversible dinucleotide model.

  • Neighboring nucleotides exert a striking influence on mutation, with the hypermutability of CpG dinucleotides in many genomes being an exemplar.

  • So this is illustrated with a single dinucleotide with two states.

  • Differences in size of as little as one dinucleotide can be detected.

  • So here is our dinucleotide, slightly skewed, but OK.

  • Some of the conclusions of this paper may be influenced by their choice of the dinucleotide mutation rate:

  • Now we generalize by defining a dinucleotide rate matrix as follows:

  • The basis of this polymorphic variation is a difference in the number of dinucleotides within (CA)n and other simple sequence repeats.

  • In real biological sequences, the frequencies of dinucleotide and higher-order tuples are not products of their monomer frequencies.

Morphology

dinucleotide = nucleotide (transparent) = di + nucleotide

Formed by the productive numeric prefix 'di-' meaning 'two' plus 'nucleotide'; meaning 'two nucleotides joined' is a direct morphological combination (though the term is technical).

Etymology

Dinucleotide breaks into di- meaning 'two', as in bicycle, and nucleotide, from nucleus meaning 'center', which names the small parts that make up DNA. So a dinucleotide is simply two nucleotide 'units' joined together.
