The moons orbit is 27 days.
I believe reducing our co2 emmisions would reduce wave erosion because the sea level would lower, meaning waves wouldnt getas far or high as they do now.
Answer:
The correct answer is option E. "nucleotides can only be added to an available 3'-OH group on the transcript terminus".
Explanation:
RNA synthesis is catalyzed by an enzyme called RNA polymerase. RNA polymerase always catalyze the synthesis of new RNA from 5' to 3' because nucleotides can only be added to an available 3'-OH group on the transcript terminus. This has been confirmed in labeling experiments with γ-32P substrates which establish the presence of a triphosphate moiety in transcripts with either pppG or pppA.
