👉 A mononucleotide is a nucleic acid that does not contain any nucleotides and has no repeating sequences of nitrogenous bases. Mononucleotides are characterized by their lack of a repeat sequence, which can make them difficult to visualize or identify in DNA samples. They are also known as "non-coding" nucleic acids because they do not carry genetic information. Mononucleotides are often found in the nucleus of cells and are involved in the regulation of gene expression
