Which section of the pre-mrna contains the protein-coding regions
raketka [301]

The exons of the pre -mRNA contain the protein -coding regions.

Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.

The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.

RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins.  These SnRNPs make the spliceosome, which catalyzes the process of splicing.

After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.
