Q. 11. Do you think that the alternative 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?
Functional mRNA of structural genes need not always include all its exons. This alternate splicing of exons is sex-specific, tissue-specific and even developmental stage-specific. By such alternate splicing of exons, a single gene may encode for several isoproteins and/ or proteins of a similar class.
In absence of such a kind of splicing, there should have been new genes for every protein/isoprotein. Such an extravagance has been avoided in natural phenomena by way of alternate splicing.
