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?

Question

Quizplus · Accepted Answer

Eukaryal cells process the pre-mRNA molecule by capping the 5' end with 7-methyl-guanosine, adding a poly-A sequence at the 3' end, and removing internal sequences called introns. This process is called RNA splicing, and it results in the mature mRNA molecule. This process is more complex than in bacterial cells, which only need to add a termination signal to the mRNA molecule. Option A, B and D are incorrect because they suggest that exons are removed, which is not true. Option E is incorrect because it suggests capping the 3' end, whereas capping occurs at the 5' end.
