Which of the following eukaryotic transcription events is directly related to the dephosphorylation of a molecule? a. recruitment of capping factors to the ctd tail of rna polymerase promoter escape b. recruitment of splicing factors to the ctd tail of rna polymerase formation of a 5′ rna cap

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.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
