Within the transcription bubble,the first 9 bases of a newly synthesized RNA strand temporarily form a helix with the template DNA strand.How might transcription be affected if helix formation could not occur?
A)Clearance of the promoter will be inhibited.
B)The RNA polymerase will be unable to unwind the DNA duplex.
C)The position of the 5' end of the RNA will be unstable,inhibiting elongation.
D)The position of the 3' end of the RNA will be unstable,inhibiting elongation.
