Key Difference – Oligonucleotide vs Polynucleotide Nucleotides are the basic structural units that synthesize complex polymeric forms of both DNA (deoxyribose nucleic acid) and RNA (ribose nucleic acid). Nucleotides are organic molecules. They are composed of three basic subunits: a nitrogenous base, pentose sugar (ribose/deoxyribose) and a phosphate group. The DNA and RNA synthesized […]
