During post-transcription processing of mRNA in eukaryotes
A) the primary transcript is 'capped' by the addition of a modified guanosine triphosphate residue to the 5' end.
B) the primary transcript is 'capped' by the addition of a modified guanosine triphosphate residue to the 3' end.
C) the promoter sequence is removed from the 5' end of the mRNA and a modified guanosine tri phosphate is added to the 3' end.
D) the 5' end of the transcript is cleaved, and a poly A 'tail' is added to the new 5' end.
E) the primary transcript is 'capped' by the addition of a modified guanosine triphosphate residue to the 3' end and the promoter sequence is removed from the 5' end of the mRNA and a modified guanosine tri phosphate is added to the 3' end.

During post-transcription processing in eukaryotes, the primary transcript is indeed 'capped' at the 5' end with a modified guanosine triphosphate residue, which helps in mRNA stability and initiation of translation.
