Answer;

RNA contains uracil (U) instead of Thymine (T)

Explanation;

  • Nucleic acids are among the four major biomolecules in nature others being lipids, carbohydrates, and proteins.
  • Nucleic acids are classified into two; Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).

The two nucleic acids have got similarities and also differ structurally in a number of ways.

  • They are both made up of nucleotides which are the building blocks.
  • DNA is double stranded while RNA is single stranded.
  • RNA contains a nucleotide uracil (U) in place of Thymine (T) in the DNA.
  • DNA is only found in the nucleus while RNA is found in the cytoplasm and also in the ribosomes where proteins are synthesized.
