All of these choices are correct. In eukaryotes, post-transcriptional modifications include polyadenylation (adding a poly(A) tail to mRNA), intron removal (splicing out non-coding sequences), and 5' cap addition (adding a modified guanine nucleotide to the 5' end of mRNA). These modifications are essential for mRNA stability, nuclear export, and translation.
