Academic session 2026-27, Chapter 5 in the current curriculum.
Welcome to the NCERT Solutions for Class 12 Biology - Chapter Molecular Basis of Inheritance. This page offers a step-by-step solution to the specific question from Exercise 0, Question 22:
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?
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?
Functional mRNA of structural genes need not always include all of its exons. This alternate splicing of exons of sex- specific, tissue specific and even developmental stage- specific. By such alternate splicing of exons, a single gene may encode for several isoproteins.
In the absence of such kind of splicing, there should have been new variety of genes for every protein/ isoprotein. This extravagancy has and should been avoided in natural phenomena by way of alternate splicing.
