Nucleic acids

Explanation:

Nucleic acids are one of the the four major biological molecules in living systems (the other three being; carbohydrate, protein, and lipids). Nucleic acid is a biological polymer that is made up of monomeric units called NUCLEOTIDES.

Nucleotides, are monomers of nucleic acids that consists of a 5-carbon sugar (ribose or deoxyribose), nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil) and a phosphate group (PO34-). Ribonucleic acid (RNA) are deoxyribonucleic acid (DNA) are the two types of nucleic acids.
