Question

every dna molecule is made up of molecules called
choose one option
a chromosome quads.
b mutational pairs.
c nucleotides.
d mitochondria.

Explanation:

To solve this, we analyze each option:

• Option A: "chromosome quads" is not a valid term for DNA building blocks. Chromosomes contain DNA, not the other way around in terms of this description.
• Option B: "mutational pairs" is incorrect. Mutations are changes in DNA, not the basic units of DNA.
• Option C: Nucleotides are the basic building blocks of DNA. A DNA molecule is composed of nucleotide units.
• Option D: Mitochondria are organelles in cells, not the molecules that make up DNA.

Answer:

C. nucleotides.
