RNA polymerase III transcribes
A
mRNAs
B
tRNAs
C
Reverse transcriptase
D
ssDNA
Answer
tRNAs
Explanation
Solution
Eukaryotes have three RNA polymerases. RNA polymerase I is located in the nucleolus and transcribes for rRNAs. RNA polymerase II is localized to the nucleo- .plasm and used for hnRNA, mRNA. RNA� polymerase Ill, is localized to the nucleus, possibly the nucleolar-nucleoplasm interface and transcribes for tRNA, 5srRNA and snRNAs. Prokaryotes have only one RNA polymerase which synthesizes all types of RNAs
