Answer:

Nucleic acids are not essential for nutrition

Explanation:

Nucleic acids are a group of biomolecules that functions in the storage and transmission of genetic material within living organisms. DNA is one of the nucleic acids found in nature.

DNA is a storage molecule i.e stores genetic information. It does not store energy, hence, it doesn't serve the purpose of providing nutrient in a cell. Therefore, DNA will not be included on the nutrition labels for strawberries because they are not essential biomolecules for nutrition.
