    Intron transcripts in heterogeneous nuclear RNA (7mRNA)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 :

    Heterogeneous nuclear RNA (hmRNA) 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 RNA (snRNA) is involved in RNA splicing. The snRNAs form a macromolecular complex called spliceosome.
