Question
1)
After transcription, nuclear RNA is capped, polyadenylated, spliced. After successful splicing, proteins are added to the mature mRNA at the exon junction complex and then transported to the cytoplasm. Which of the following is a NOT a reason why these modifications are added to mRNA?
1. to aid in transport from ribosome to cytoplasm through pore
2. to stabilize mRNA molecule
3. to signal to the cell that mRNA is ready for translation
4. to identify the RNA molecule as mRNA
