Monomers are the building blocks that make up nucleic acid. Also known as nucleotides, they are composed of a five-carbon sugar, a nitrogenous base and a phosphate group.
For carbohydrates, the monomer is called a monosaccaride, its polymer is called a polysaccaride which is just a chain of many monosacchrides. DNA and RNA are nucleic acids and work in just the same way. A monomer of a nucleic acid is called a nucleotide which consists of a sugar, phosphate group and nitrogen containing base. many nucleotides put together forms a polymer nucleotides which is call nucleic acids. Thus the polymer of DNA and/or RNA is a nucleic acid. Source(s): i am a senior at UCLA, majoring in biochemistry and minoring in anthropology.
