The following statements are with respect to transcription in eukaryotes. Choose the correct ones.
(i) The strand of dsDNA which takes part in transcription process is called as coding strand.
(ii) The enzyme RNA polymerase can catalyse polymerisation only in one direction i.e., $5\text{'}\to 3\text{'}$ .
(iii) An unusual nucleotide methyl guanosine triphosphate is added to the $5\text{'}$ end of hnRNA during capping.
(iv) During tailing process, adenylate residues $\left(200-300\right)$ are added at $3\text{'}$ end in a template independent manner.

In the given transcription unit, identify the regions $\mathrm{I}$ and $\mathrm{II}$ respectively. Coding strand

Two of the following statements are correctly defined. Identify the correct combination

i) Conversion of hnRNA to mRNA - processing

ii) Removal of introns and joining of exons - splicing

iii) Addition of adenylate residues to $3\text{'}$- end in a template dependent manner - Tailing

iv) Methyl adenosine triphosphate is added to $5\text{'}$ - end of hnRNA - capping
