Every DNA molecule is made up of smaller molecules called nucleotides.

What DNA Is Made Of

Each DNA molecule is a long chain (polymer) built from repeating units called nucleotides, often described as the “building blocks” of DNA. Each nucleotide in DNA has three main parts: a phosphate group, a sugar called deoxyribose, and one nitrogenous base (adenine, thymine, cytosine, or guanine).

Because of this, textbooks and quizzes usually complete the sentence “Every DNA molecule is made up of molecules called ____” with the word nucleotides.

Mini Breakdown: Nucleotides

• One nucleotide = phosphate + deoxyribose sugar + one base (A, T, C, or G).

• Many nucleotides linked together form a long DNA strand, and two such strands twist into the double helix.

• Focus phrase: every dna molecule is made up of molecules called → answer: nucleotides.

• Meta-style description:
  Every DNA molecule is made up of repeating units called nucleotides, each containing a sugar, a phosphate group, and a nitrogen base that together store genetic information.
