C)	Tailing	III)	Lagging strand
D)	Promoter	IV)	Methyl guanosine triphosphate
		V)	Adenylate residues

• A. A - II, B - IV, C - V, D - I
• B. A - II, B - IV, C - I, D - V
• C. A - III, B - I, C - II, D - IV
• D. A - IV, B - II, C - III, D - I

Answer 1

The correct option is A A - II, B - IV, C - V, D - I

Exon is any part of the gene that will become a part of the final mature RNA, in short, it is a coding sequence.
Capping is the process whereby a 5' cap is attached to the mRNA molecules that are in the process of being synthesized in the cell nucleus. The 5' cap is a chemical cap as N7-methylguanosine triphosphate.
Tailing is the process where there is an addition of a poly-adenylate to an mRNA.

The promoter is a region of DNA that initiates the transcription of a particular gene, where the RNA polymerase enzyme can bind to.

Thus, the correct answer is the option (A).
