Biology Question on the molecular basis of inheritance
Among the RNA polymerases, the RNA polymerase-II transcribes
A
rRNA
B
fRNA
C
small nuclear RNAs
D
heterogeneous nuclear RNA
Answer
heterogeneous nuclear RNA
Explanation
Solution
RNA polymerase II occur in nucleoplasm (a part of nucleus). It is a major component of RNA polymerase activity and transcribe mRNA producing gene. In eukaryotic organisms it transcribes hnRNA (an intial form of mRNA precursor) which are late on processed into mRNA, while m-RNA are transcribed by RNA polymerase-I.
