Which of the following statements regarding the transcription and mRNA processing in eukaryotes is NOT correct? Choose one: A. Hyperphosphorylation of the RNA polymerase II CTD regulates the interaction of mRNA processing enzymes with the newly transcribed regions of mRNA. B. Transcription factors (TFIIA, TFIIB, TFIIE, TFIIH) assemble on RNA polymerase II after it binds to TFIID/TBP. C. Capping of the mRNA 5' end occurs co-transcriptionally. D. Splicing of the mRNA occurs co-transcriptionally.

This is because hyperphosphorylation of the RNA polymerase II C-terminal domain (CTD) plays a crucial role in recruiting mRNA processing enzymes to the newly transcribed mRNA. Show more…

Which of the following statements is true about transcription & translation? In prokaryotes, transcription stops right at the terminator and transcribes additional sequence, while in eukaryotes, RNA polymerase II synthesizes mRNA directly from DNA. In eukaryotes, RNA polymerase II can recognize and bind directly to the promoter region. In eukaryotes, pre-mRNA is synthesized directly from DNA, which then travels to the cytoplasm to be translated into protein. In prokaryotes, transcription and translation are coupled, while in eukaryotes, both processes happen at the same site but at different times.
