During rna processing a(n) is added to the 5' end of the rna.
(a)-3' untranslated region
(b)-a long string of adenine nucleotides
(c)-5' untranslated region coding segment
(d)modified guanine nucleotide

The correct answer is (d)modified guanine nucleotide.

Explanation:

When the transcription process is finished, the guanine cap is added to the 5' end of the RNAm so it can be recognized in the cytosol and not scrapped. On the other hand, a long strand of adenines or Poly A tail is also added but to the 3' end, for the same purpose.
