  • Which nucleotide is not found in DNA?
    Uracil is not found in DNA.
  • Which nitrogenous base is found in DNA nucleotides but not in RNA nucleotides?
    Thymine is found in DNA nucleotides but not RNA.
  • Which nitrogenous base is present in RNA but not in DNA?
    RNA has Uracil, which DNA does not have.
  • Which of the nitrogenous bases below would be classified as purines?
    Adenine and Guanine are classified as purines.
  • What is the difference between purines and pyrimidines?
    Purines have a double-ring structure, while pyrimidines have a single-ring structure.
  • What part of the nucleotide has a slightly negative charge?
    The phosphate group of a nucleotide has a slightly negative charge.
  • Which nitrogen bases are complementary to each other?
    Adenine pairs with Thymine (or Uracil in RNA), and Cytosine pairs with Guanine.
