The Building Blocks of DNA are Called ________

Question

The building blocks of DNA are called ________.
A) amino acids
B) codons
C) nucleotides
D) alleles

Accepted Answer

The building blocks of DNA are nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. Amino acids are the building blocks of proteins, not DNA. Codons are sequences of three nucleotides that encode a specific amino acid, not the building blocks of DNA itself. Alleles refer to different versions of a gene, not the building blocks of DNA.
