The sequence of nitrogen bases in a particular region of the non-coding strand of a DNA molecule was found to be $\mathrm{CAT} \mathrm{GTT} \mathrm{TAT} \mathrm{CGC}$. What would be the sequence of nitrogen bases in the mRNA that is synthesized by the corresponding region of the coding strand in that DNA?

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
