Questions
In eukaryotes, RNA Polymerase III catalyses the synthesis of :
a
all rRNA and tRNA
b
mRNA, hnRNA and snRNA
c
5s rRNA, tRNA and snRNA
d
28S, 18S and 5S rRNA.
detailed solution
Correct option is C
RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs). The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA). The RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S).Talk to our academic expert!
