Usage: biochemistry term; commonly used in molecular biology and genetics

Examples

• A dinucleotide is the basic building block formed when two nucleotides bond together.
• The dinucleotide adenosine-guanosine is found in various biological molecules.
• Researchers studied how dinucleotides combine to form longer DNA and RNA strands.
• The enzyme cleaved the dinucleotide into its two separate nucleotide components.
• Dinucleotides serve as important intermediates in nucleic acid synthesis.
