Answer to Question #213925 in General Chemistry for jojo malik

Question

 You have detected a novel uncharacterized RNA which you named Rawal-RNA (It could be mRNA/tRNA/rRNA). When you treat cells with a low dose of alpha-­amanitin, levels of Rawal--RNA and GAPDH mRNA DECREASE drastically, whereas tRNA and rRNA levels are unchanged.

 a) Which RNA polymerase makes RawalRNA? 

b) Explain your reasoning

Answer 1

a) RNA polymerase

b) The task of transcribing nuclear genes is shared between three RNA polymerases in eukaryotes: RNA polymerase (pol) I synthesises the large rRNA, pol II synthesises mRNA and pol III synthesises tRNA and 5S rRNA.
