In the context of DNA structure, DNA is made up of repeating subunits called what?
A
Amino acids
B
Nucleotides
C
Monosaccharides
D
Fatty acids
Verified step by step guidance1
Understand that DNA is a polymer, meaning it is made up of many repeating smaller units linked together.
Recall that the basic building blocks of DNA are not amino acids (which build proteins), monosaccharides (which are simple sugars), or fatty acids (which are components of lipids).
Identify that the repeating subunits of DNA are called nucleotides, each consisting of a sugar, a phosphate group, and a nitrogenous base.
Recognize that nucleotides link together through phosphodiester bonds to form the long DNA strand.
Conclude that the correct term for the repeating subunits of DNA is nucleotides.
