Mature mRNA from a eukaryote would contain each of these features except which of the following?

exon-encoded RNA

intron-encoded RNA

5’ cap

3’ poly-A tail

intron-encoded RNA

Explanation:

Introns are the sequences that do not code for any proteins. The newly formed RNA of eukaryotes have both introns and exons. Introns are removed from the RNA through the process of splicing during post-transcriptional modifications.

The mature mRNA from eukaryotes do not have introns. During splicing, introns are removed from the primary transcript and exons are joined together in a continuous manner.
