The transcription elongation phase in prokaryotes begins with the release from the polymerase of the:
APromoter region
BRibosomal RNA
CSigma subunit
DTemplate strand
Answer & Solution
Correct answer: C. Sigma subunit
1. Elongation is marked by a specific departure from the enzyme.
2. Transcription in prokaryotes moves from initiation into elongation.
3. The transcription elongation phase begins with the release of the sigma subunit.
4. It is released from the polymerase.
