Given below are two statements: Statement I: In eukaryotes there are three RNA polymerases in the nucleus in addition to the RNA polymerase found in the organelles. Statement II: All the three RNA polymerases in eukaryotic nucleus have different roles. In the light of the above statements, choose the correct answer from the options given below:Eukaryotes have three nuclear RNA polymerases (I, II, III) in addition to the RNA polymerase found in organelles (mitochondria/chloroplast), so Statement I is true. RNA polymerase I transcribes rRNAs, RNA polymerase III transcribes tRNA and other small RNAs, and RNA polymerase II transcribes precursor of mRNA — each has a distinct role, so Statement II is also true.
