Coastal mountains force cool, moist air from oceans to rise as it moves toward land. Clouds form, and precipitation falls on the <u>windward</u> side of the mountain. On the <u>leeward</u> side of the mountain, very little precipitation falls.
Answer:
d. RNA polymerase II.
Explanation:
The main enzyme responsible for RNA synthesis is RNA polymerase, which <em>catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) </em>directed by a DNA mold.
Eukaryotic cells contain <u>three types of nuclear RNA polymerases</u> that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.
