Biology How Does the CTD of RNA Polymerase in Eukaryotes Affect Transcription?

[hidemi]

Homework Statement

Which process is associated with the carboxy-terminal domain (CTD) of RNA polymerase II in eukaryotes?
A) formation of spliceosomes
B) attachment of the 5' cap to mRNA
C) polyadenylation of the 3' end of mRNA
D) phosphorylation and dephosphorylation
E) All of the answers are correct

The answer is E

Relevant Equations

None

How can A, B, and C choices do with the CTD?

 

[Ygggdrasil]

RNA transcribed by RNAP II is processed to mature RNA through the steps of 5′ capping, intron removal, and 3′ end formation. These processes are frequently coupled with transcription, and all involve the CTD
