Types of RNA polymerase required in nucleus for RNA synthesis
A
1
B
2
C
3
D
4
Answer
3
Explanation
Solution
In eukaryotic cells, there are multiple types of RNA polymerase enzymes responsible for different types of RNA synthesis. The RNA polymerase required in the nucleus for RNA synthesis includes 3. RNA polymerase I is responsible for the synthesis of ribosomal RNA (rRNA), RNA polymerase II is responsible for the synthesis of mRNA (messenger RNA), and RNA polymerase III is responsible for the synthesis of small RNA molecules, including transfer RNA (tRNA) and some small nuclear RNAs (snRNAs). These three RNA polymerases are primarily responsible for RNA synthesis in the nucleus of eukaryotic cells. So, the correct option is (C): 3
