Q. 6

Evolution has exhibited a greater stability of molecular structure when compared with morphological structures. Comment on the statement and justify your opinion.

Answer :

Molecular structure is the smallest component with which an organism is made up of while the morphological structure is the external structure of an organism which can be seen by us. The diversity, in organisms, that we see around is because of diversity in morphological structure. When we look at the molecular level all the organisms are made up of same biomolecules. DNA, protein, lipid, carbohydrates, etc. The DNA structure is same in all organisms but the count of DNA may vary. Irrespective of the type of organism, a DNA molecule or a protein molecule would have the same structure. Hence, it can be said that molecular structures show great stability.
