30. A prokaryote experiment was conducted to determine the hairpin loop region in termination. Two DNA templates were prepared and used in an in vitro transcription assay. The samples were analyzed for release of the RNA polymerase. Construct 1 - hairpin sequence removed;
Construct 2 - two copies of hairpin sequence inserted; Construct
3 - normal DNA with only one hairpin sequence The data from this experiment suggest that

(A) hairpin loops are not required for termination. polymerase.
(B) two hairpin loops rapidly destabilize the
(C) the data are inconclusive.
(D) additional hairpin loops increase the stability of the RNA:DNA hybrid.
