Question

During transcription in eukaryotes, the enzyme responsible for synthesis of mRNA is:

• A. DNA polymerase
• B. RNA polymerase I
• C. RNA polymerase II
• D. RNA polymerase III

Hint:

Remember:
• Pol-I \(\rightarrow\) rRNA
• Pol-II \(\rightarrow\) mRNA
• Pol-III \(\rightarrow\) tRNA

Answer 1

The Correct Option is C

Concept: Eukaryotes possess three major RNA polymerases:
• RNA polymerase I
• RNA polymerase II
• RNA polymerase III Each synthesizes different types of RNA.

Step 1: Functions of RNA polymerases.
• RNA polymerase I \(\rightarrow\) rRNA
• RNA polymerase II \(\rightarrow\) mRNA
• RNA polymerase III \(\rightarrow\) tRNA

Step 2: Identifying enzyme for mRNA synthesis. Messenger RNA is synthesized by: \[ \boxed{\text{RNA polymerase II}} \] Final Answer: \[ \boxed{(C)\ \text{RNA polymerase II}} \]
