    C)                 intron   

    D)                 exon

    Correct Answer: B

    Solution :

                    In eukaryotes, the regulation of gene expression involves splicing together of exonic portions of RNA to give rise to functional m-RNA.                 Introns are DNA sequences lying within a coding sequence, but not usually encoding cell product.                 Exon is a DNA sequence encoding and gives rise to a translated polypeptide sequence (protein).
