Which statement correctly describes the transcription of DNA?
Correct answer: B. It produces mRNA
- A. It produces another DNA molecule
- B. It produces mRNA
- C. It is a semi conservation process
- D. It occurs at surface of ribosomes
Explanation
Transcription uses one DNA strand as a template to synthesize a complementary RNA molecule, commonly mRNA for a protein-coding gene. It occurs in the nucleus of eukaryotic cells, whereas ribosomes use mRNA during translation in the cytoplasm. Students may choose semi-conservative replication because DNA is involved, but semi-conservative copying produces DNA, not mRNA.
