← Assertion (A): DNA is preferred to RNA for the storage of genetic information. Reason (R): The 2'-OH group present at every nucleotide of RNA is a reactive group, and it makes RNA labile and easily degradable.Read the following statements about the criteria that a molecule must fulfil to act as genetic material.
(i) It should be able to generate its replica.
(ii) It should be chemically and structurally stable.
(iii) It should provide scope for slow changes (mutation) that are required for evolution.
(iv) It should be able to express itself in the form of Mendelian characters.
(v) It should act as a catalyst for the reactions of the cell.
(vi) Proteins fulfil the first criterion, so they too could serve as genetic material.
