    Solution:

    The primary transcript of monocistron of eukaryotes is called heterogenous nuclear RNA (hnRNA). It has regions with information for the formation of proteins (exons) and also alternating intron sequences (regions without any information for protein formation). Such RNA is processed by splicing to make it as functional mRNA or active mRNA.
