alleryTranscription differs from replication in that it
Acopies the entire genome (typical)
Bcopies only a portion of one DNA strand into RNA
Cuses DNA as both template and product
Dneeds no enzyme
Answer & Solution
Correct answer: B. copies only a portion of one DNA strand into RNA
1. Transcription synthesises RNA using one DNA strand (the template) as a guide.
2. Only specific gene regions are transcribed, not the whole genome at once.
3. The enzyme RNA polymerase catalyses the process; no primer is needed.
