The main role of mRNA during protein synthesis is to:
Correct answer: A. Carry genetic information for protein synthesis
- 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.

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
