The correct answer is "formation of a 5′ RNA cap"

Explanation:

The five-prime cap (5′ cap) RNA is a precursor form of messenger RNA. The creation of 5′ RNA cap, known as mRNA capping, is an essential process for messenger RNA maturation that results in the proper translation of proteins. The creation of 5′ RNA cap is directly related to dephosphorylation because the first step of mRNA capping is the dephosphorylation of the terminal phosphate groups of RNA, catalyzed by the enzyme RNA triphosphatase.
