Nucleic acids
Definition
Nucleic acids are biological macromolecules made from nucleotides that store, transmit and help express genetic information.
Formula / Key Relation
A nucleotide contains: a sugar; a phosphate group; * a nitrogen-containing base. DNA is made from many nucleotides arranged in long chains. RNA is also a nucleotide polymer but differs in sugar type, bases and typical structure. Nucleotide: `sugar + phosphate + nitrogenous base` DNA bases: A, T, G, C RNA uses: A, U, G, C
