- pentose sugar (5-carbon)

- nitrogenous bases:

  • thymine (T) DNA only
  • uracil (U) RNA only

Stores and carries genetic information

Nucleic Acids: Food Sources

We get nucleic acid components from vitamins and minerals in our diet. These in turn, come from fruits, vegetables, grains, meats, & almost anything else you can think of with some nutritional value (no junk food!).
