According to the text, a molecule that acts as genetic material must fulfill four criteria: (i) It should be able to generate its replica (Replication); (ii) It should be chemically and structurally stable; (iii) It should provide the scope for slow changes (mutation) that are required for evolution; and (iv) It should be able to express itself in the form of 'Mendelian Characters'. Therefore, the statement that it 'Should not provide the scope for changes for evolution' is incorrect .
