Given below are two statements: Statement I: In eukaryotes, RNA polymerase III is responsible for the transcription of tRNA, 5S rRNA, and snRNAs. Statement II: RNA polymerase II transcribes the 28S, 18S, and 5.8S rRNAs in the eukaryotic cell. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Statement I and Statement II are correct
- BBoth Statement I and Statement II are incorrect
- CStatement I is correct but Statement II is incorrect
- DStatement I is incorrect but Statement II is correct
Correct answer
C. Statement I is correct but Statement II is incorrect
Step-by-step solution
In eukaryotes, there are three major types of RNA polymerases: RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S). RNA polymerase II transcribes the precursor of mRNA, the heterogeneous nuclear RNA (hnRNA). RNA polymerase III is responsible for the transcription of tRNA, 5S rRNA, and small nuclear RNAs (snRNAs). Therefore, Statement I is correct, while Statement II is incorrect because RNA polymerase I (not II) transcribes 28S, 18S, and 5.8S rRNAs. Answer: Statement I is correct but Statement II is incorrect
