Explanation:
When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to transcriptional termination.
Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .
When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.
The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.

Choice two and five are correct!
Answer:
False
Explanation:
Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.
Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.
Thus,
Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.
