Final answer:
The primary function of nucleic acids is to store information. They carry the genetic blueprint and contain instructions for the functioning of a cell. DNA is double-stranded and stores the complete genetic information required for specifying the structure of proteins and RNA in an organism.
Step-by-step explanation:
The primary function of nucleic acids is to store information. Nucleic acids, such as DNA and RNA, carry the genetic blueprint of a cell and contain instructions for the functioning of the cell. DNA stores the complete genetic information required to specify the structure of all the proteins and RNA's of each organism. DNA is double-stranded and contains the instructions for protein synthesis, while RNA is involved in the production of proteins.
