Question

Main function of mRNA is

• A. Acting as template for RNA
• B. DNA synthesis
• C. Protein synthesis
• D. Conversion of DNA to RNA

Answer 1

Answer: (C)

Protein synthesis

The template DNA strand serves in RNA synthesis during transcription while the other strand is called as coding strand as its base sequence is same as that of newly synthesized mRNA. Option A is incorrect. DNA polymerase enzyme adds nucleotides to synthesize DNA using the base sequence of parental DNA strand. Option B is incorrect. Primary transcript synthesized during transcription undergoes processing to produce a functional mRNA and is transported to the cytoplasm where it serves as the template for amino acid sequence of the polypeptide, synthesized during protein synthesis. Option C is correct. RNA polymerase enzyme adds ribonucleotides to synthesize RNA using the base sequence of template DNA strand. Option D is incorrect.

Thus, the correct answer is option C.
