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.

Answer:</h2>
<h3>In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.</h3>
Photosynthesis produces oxygen, which we use to breathe.
Potential energy = (mass) x (gravity) x (height) .
To raise the 20kg block 6 meters, you need to give it
(20 kg) x (9.8 m/s²) x (6 m) = 1,176 joules
of potential energy.
Your machine takes 2,000 joules of energy to give the block
the 1,176 joules that it takes.
Your machine is only (1176 / 2000) = 58.8% efficient .
The other 'missing' 824 joules of energy doesn't just disappear.
It heats the machine, and the air around it. The final result is
that when you use that machine to lift blocks, you have to use
even MORE energy, to blow cool air on the machine and prevent
it from overheating and breaking.
