    Intron transcripts in heterogenous nuclear RNA (in RNA) are removed and exon transcripts are joined together under the direction of protein complexes. These complexes are

    A)  polysomes                        

    B)  Cdk complex

    C)  spliceosomes                                   

    D)  endopeptidases

    Correct Answer: C

    Solution :

                     Heterogenous nuclear RNA (hn RNA) undergoes the process of splicing. Splicing is the controlled excision of introns from the transcript and   rejoining   of remaining fragments, called exons. A smaller nuclear RNAs (sn RNAs) is involved in RNA splicing. The sn RNAs form a macromolecular complex called spliceo some.
