Answer :
i) The enzyme which catalyses the transcription of hnRNA is the DNA independent RNA polymerase.
ii)hnRNA undergoes changes so as to convert non-functional hnRNA to functional mRNA.
The changes which take place are :
a) RNA Splicing: In this process the introns are removed from the RNA and exons are left and joined together via ligase.
b) Capping: In this process a 7-methyl guanosine triphosphate nucleotide is added to the 5’ end of the hnRNA.
c) Tailing: In this process the 3’ end is adenylated
