Verified step by step guidance1
Understand that DNA is a polymer, which means it is made up of repeating smaller units called monomers.
Recall that the monomers of DNA are not amino acids (which build proteins), fatty acids (which are components of lipids), or monosaccharides (which are simple sugars).
Identify that the monomers of DNA are called nucleotides, which consist of three parts: a phosphate group, a sugar (deoxyribose), and a nitrogenous base.
Recognize that nucleotides link together through phosphodiester bonds between the phosphate of one nucleotide and the sugar of the next, forming the backbone of the DNA strand.
Conclude that nucleotides are the fundamental building blocks of DNA, enabling it to store genetic information.
