Final answer:
Nucleic acids are the compounds that store genetic information, with DNA being responsible for storing hereditary information that is inherited from one generation to another.
Step-by-step explanation:
The word from the list that best fits the definition 'these compounds store genetic information' is d. Nucleic Acids. Nucleic acids, which include DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid), are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and provide instructions for the functioning of the cell. DNA specifically stores the complete genetic information required to specify the structure of all the proteins and RNAs of an organism and is passed from one generation to the next, ensuring hereditary continuity.
