In DNA structure, DNA is composed of repeating subunits called what?
A
Monosaccharides
B
Nucleotides
C
Fatty acids
D
Amino 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 composed of three parts: a sugar molecule, a phosphate group, and a nitrogenous base.
Identify that these smaller units are called nucleotides, which are the repeating subunits of DNA.
Recognize that monosaccharides are simple sugars, fatty acids are components of lipids, and amino acids are building blocks of proteins, so these are not the correct subunits for DNA.
Conclude that the correct term for the repeating subunits of DNA is nucleotides.
