A molecule made of two nucleotides bonded together, the basic building blocks of DNA and RNA.
From Latin prefix 'di-' (two) + 'nucleotide,' which comes from 'nucleus' (kernel) + Greek 'nucleon,' formed in the mid-20th century as molecular biology vocabulary.
Dinucleotides are like the LEGO bricks of LEGO bricks—while DNA contains millions of nucleotides, scientists study dinucleotides because their simple structure reveals how genetic information actually binds and codes in your cells.
