Elongation, termination of transcription, and RNA processing are interconnected, presumably to ensure their proper coordination,

Elongation factors
I.    hSPT5	To recruit the 5’ -capping enzyme to the CTD tail of polymerase
II.   TAT-SF1	To recruits components of the splicing machinery to polymerase with a Ser-2 phosphorylated tail

The final RNA processing event, polyadenylation of the 3’end of the mRNA, is intimately linked with the termination of transcription. Just as with capping and splicing, the polymerase CTD tail is involved in recruiting some of the enzymes necessary for polyadenylation,
