Which of the following is the primary role of mRNA in protein synthesis?
- Forming the structure of the ribosome.
- Catalyzing peptide bond formation.
- Transporting amino acids to the ribosome.

What is the significance of replacing thymine with uracil in RNA?
What is the significance of replacing thymine with uracil in RNA?
- Uracil allows RNA to form stronger base pairs, enhancing its structural integrity.
- Uracil provides greater stability to the RNA molecule compared to thymine.
- Uracil signals that the molecule is RNA, distinguishing it from DNA and preventing inappropriate DNA repair mechanisms. (correct)
- Uracil is easier to synthesize, making RNA production more efficient.
