Final answer:
Nucleic acids are macromolecules made up of nucleotides that carry genetic information and instructions for cell functioning. The two main types are DNA and RNA.
Step-by-step explanation:
Nucleic acids are macromolecules made up of monomers called nucleotides. They carry the genetic information of a cell and instructions for the functioning of the cell. Nucleic acids are information molecules that serve as blueprints for the proteins made by cells. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
