Explanation:

DNA is a polymer made up of repeating units called nucleotides. Each nucleotide consists of a sugar - deoxyribose, a phosphate group, and a nitrogen - containing base (adenine, thymine, guanine, or cytosine). Amino acids are the monomers of proteins. Sugar alone is not the monomer of DNA. Guanine is one of the bases in a nucleotide. A chromosome is a structure that contains DNA.
