Large Ribosomal RNAs are Transcribed Byــــــــــــــــــــ

Question

Large ribosomal RNAs are transcribed byــــــــــــــــــــ .
A)RNA polymerase I
B)RNA polymerase II
C)RNA polymerase III
D)None of the above

Accepted Answer

Large ribosomal RNAs (rRNAs) are transcribed by RNA polymerase I in eukaryotes. RNA polymerase II transcribes messenger RNA (mRNA), while RNA polymerase III transcribes small RNA molecules, including small nuclear RNA (snRNA) and transfer RNA (tRNA). Therefore, option A is the best choice for this question.
