Nucleic acids are large biomolecules, and include both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA carries your cells' genetic information. RNA uses this genetic information, and helps the cells make proteins.Both types of nucleic acids consist of building blocks called nucleotides, though there are some differences in the nucleotides that make up the two types of nucleic acids.he building block unit of a nucleic acid is called a nucleotide.
