Question

Quizplus · Accepted Answer

The carboxy-terminal domain (CTD) of RNA polymerase II in eukaryotes is involved in several key processes during transcription and post-transcriptional modifications of mRNA. These include the formation of spliceosomes (A), the attachment of the 5' cap to mRNA (B), polyadenylation of the 3' end of mRNA (C), and its own phosphorylation and dephosphorylation (D), which regulate its activity and interactions with other proteins during the transcription cycle.
