Transcription Termination in Eukaryal Cells Is More Complex Than in Bacterial

Multiple Choice

Transcription termination in eukaryal cells is more complex than in bacterial cells as the RNA molecule undergoes further processing before becoming a functional mRNA.Which of these BEST describes this processing?

B) Capping the 3' end with 7-methyl-guanosine,adding a poly-A sequence at the 5' end and removing internal sequences called exons.
C) Capping the 5' end with 7-methyl guanosine,adding a poly-A sequence at the 3' end and removing internal sequences called introns.
D) Capping the 5' end with 7-methyl-guanosine,adding a poly-A sequence at the 3' end and removing internal sequences called exons.
E) Capping the 3' end with 7-methyl-guanosine and adding a poly-A sequence at the 3' end.
