Answer 1

Nucleic acids, which include RNA (ribonucleic acid) and DNA (deoxyribonucleic acid), play a crucial role in the storage and expression of genetic information. Therefore, the correct answer is:

Storage and expression of genetic information.

DNA serves as the long-term storage of genetic information, while RNA is involved in various roles, including acting as a messenger that carries instructions from DNA for controlling the synthesis of proteins.
