Multiple Choice
In the context of DNA structure, what are the building blocks (monomers) of DNA?
A
Nucleotides (each composed of a deoxyribose sugar, a phosphate group, and a nitrogenous base)
B
Fatty acids and glycerol (forming phospholipids)
C
Amino acids (linked by peptide bonds)
D
Monosaccharides (simple sugars linked by glycosidic bonds)
Verified step by step guidance1
Understand that DNA is a polymer made up of repeating units called monomers.
Identify the specific monomers of DNA, which are nucleotides.
Recognize that each nucleotide consists of three components: a deoxyribose sugar, a phosphate group, and a nitrogenous base.
Differentiate nucleotides from other biological monomers such as amino acids (which form proteins), fatty acids and glycerol (which form phospholipids), and monosaccharides (which form carbohydrates).
Conclude that the building blocks (monomers) of DNA are nucleotides, each composed of a deoxyribose sugar, a phosphate group, and a nitrogenous base.
