Solution:

Heterogeneous nucleus RNA (nRNA) undergoes the process of splicing. Splicing is the controlled excision of introns from the transcript and rejoining of remaining fragments called exons. A smallar nuclear RNA (snRNA) is involved in RNA, splicing. The snRNAs form a macromolecular complex called spliceosome.
