Which type of macromolecule stores genetic information?

Nucleic acids.

Explanation:

Nucleic acids are the polymers of nucleotides. Two types of nucleotides are deoxyribonucleic acid and oxyribonucleic acids. DNA is the genetic material of the organisms.

DNA is the hereditary material that can transmit the information from one generation to the next generation. DNA stores the genetic material and the arrangement of different nucleotides codes for the different protein product.

Thus, the answer is nucleic acids.
