Which of the following post-transcriptional modifications is essential for the nuclear export, translation, and stability of mRNA?
Understand the Problem
The question is asking which post-transcriptional modification is essential for mRNA's nuclear export, translation, and stability. We need to evaluate the roles of each of the listed modifications to determine which one is crucial for all three processes.
Answer
5' capping, splicing, and 3' polyadenylation.
Post-transcriptional modifications like 5' capping, splicing, and 3' polyadenylation are essential for nuclear export, translation, and the stability of mRNA.
Answer for screen readers
Post-transcriptional modifications like 5' capping, splicing, and 3' polyadenylation are essential for nuclear export, translation, and the stability of mRNA.
More Information
Post-transcriptional modifications are crucial steps in gene expression, ensuring that mRNA is properly processed and functional.
Tips
A common mistake is to think only one modification is responsible. All three modifications work together.
