Answer #1

1. During the post-transcriptional modification the pre-mRNA is modified. This occurs by the intron splicing and the addition of the adenine group t the 3' end. At the 5' end of the RNA, a guanine group is added which acts as the cap of the RAn. the function of this cap is to prevent RNA transcript protection from degradation and identification of the translation start site.

The answer is B.
