11. The main role of mRNA during protein synthesis is to:
- A. Carry genetic information for protein synthesis
- B. Stabilize ribosome
- C. Deliver amino acids
- D. Provide platform for proteins synthesis
Explanation: Messenger RNA is transcribed from a gene and carries that base sequence out of the nucleus to the ribosome, where it is read in triplets. Delivering amino acids is the job of transfer RNA and providing the platform is the job of ribosomal RNA, so each of the three RNAs appears once among the options. Using a working copy protects the original DNA from the risks of the cytoplasm.
Correct answer: Carry genetic information for protein synthesis
