Which of the following statements regarding nucleic acids is/are corre...
  • Statement i is correct because nucleic acids are indeed made up of polynucleotides that include ribose in RNA and deoxyribose in DNA.
  • Statement ii is incorrect; the building blocks of nucleic acids are nucleotides, not amino acids (which are the building blocks of proteins).
  • Statement iii is correct as it accurately lists the nitrogenous bases found in nucleic acids.
  • Statement iv is incorrect; DNA contains deoxyribose, while RNA contains ribose.
Thus, the correct answer is C: i, iii, and iv.
