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:
Muscular strength exercises build neuropathways to your brain, strengthening and building your muscle. Muscular endurance exercises work the muscle you already have. For example, weight lifting would be muscular strength because you're building muscle. Running would be muscular endurance because you're seeing how long those leg muscles can last. However, the two can also "intermix" and you usually do both at the same time.
A protein coat, and some DNA or RNA that isn't normal for a typical human cell.
Hey there!
Here are some possible functions of these proteins:
- They transport molecules.
- They transport messages from cell to cell.
- They catalyse reactions in our bodies.
Hope this helps you!
