A
Fatty acids
B
Monosaccharides
C
Amino acids
D
Nucleotides
Verified step by step guidance1
Understand that DNA is a polymer, meaning it is made up of many repeating units linked together.
Recall that the basic building blocks of DNA are not fatty acids, monosaccharides, or amino acids, but a specific type of molecule.
Identify that each repeating unit in DNA consists of three components: a phosphate group, a sugar (deoxyribose), and a nitrogenous base.
Recognize that these repeating units are called nucleotides, which are the fundamental structural units of DNA.
Conclude that DNA is composed of repeating structural units called nucleotides.
