Which component is not found in the nucleotide of DNA?

  • A. Simple sugar
  • B. Nitrogen base
  • C. Phosphate group
  • D. Citric acid
Correct Answer: D

Rationale: Citric acid is not found in the nucleotide of DNA. A DNA nucleotide is composed of a simple sugar (deoxyribose), a nitrogen base (adenine, thymine, cytosine, or guanine), and a phosphate group. Citric acid is not part of DNA nucleotides; instead, it is involved in the citric acid cycle of cellular respiration. Choices A, B, and C are essential components of DNA nucleotides, making them incorrect answers.
