Nucleotides: The Molecular Powerhouses

Functions of Nucleotides in DNA and RNA: Nucleotides serve critical functions in both DNA and RNA molecules. In DNA, nucleotides act as the building blocks of the famous double-helix structure. They link together through phosphodiester bonds, forming a chain with the sugar-phosphate backbone and the nitrogenous bases projecting inward. The sequence of nucleotides determines the genetic information encoded in the DNA molecule.
