Do you think that the alternate splicing of exons may enable a structural gene to code for several isoproteins from one and the same gene? If yes, how? If not, why so?

Explanation

In higher eukaryotes, mRNA is produced as hnRNA. it undergoes splicing, by which functional segments (exons) of mRNA are brought together and introns are removed, Each cell produces several isoproteins or proteins of similar function at different Stages during development and tissue differentiation, in different tissues, at different times in the cells of same tissue and ‘in different sexes.. Imagine the size of _genome if there is separate gene for each isoprotein and the control genes for the functioning of right gene at the right time.Nature has avoided this extravagancy by ‘evolving the mechanism of alternate splicing of exons of a single gene that can encode different isoproteins as required by the cell . by splicing different exons of the same gene
