Final answer:
RNA polymerase II CTD phosphorylation coordinates processes such as Promoter Escape, 5' capping, RNA splicing, and Promoter-proximal pause release during the transcription of eukaryotic genes.
Step-by-step explanation:
The phosphorylation of the RNA polymerase II C-terminal domain (CTD) is a crucial regulatory event during the process of eukaryotic transcription. The CTD of RNA polymerase II coordinates several processes of RNA synthesis and processing. Specifically, the processes coordinated by RNA polymerase II CTD phosphorylation include Promoter Escape, 5' capping, RNA splicing, and Promoter-proximal pause release. However, Translation initiation and Reverse transcription are not directly coordinated by RNA polymerase II CTD phosphorylation.
