A molecule that can act as a genetic material must fulfill the traits given below, except :-
1 It should be unstable structurally and chemically
2 It should provide the scope for slow changes that are required for evolution
3 It should be able to express itself in the form of 'Mendelian characters'
4 It should be able to generate its replica
Explanation:
The genetic material should be stable and sructurally and chemically.

Assertion : DNA is a better genetic material. Reason : DNA chemically is less reactive and structurally more stable when compared to RNA.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
DNA is more stable than RNA, because in DNA the two strands being complementary if separated by heating come together, when appropriate conditions are provided. Further, 2'-OH group present at every nucleotide in RNA is a reactive group and makes RNA labile and easily degradable. RNA is also now known to be catalytic, hence reactive.

RNA can easily express the character because
1 It has 2'-OH group at every nucleotide in its deoxyribose sugar
2 It has uracil
3 it can directly code for the synthesis of protein
4 All of the above
Explanation:
RNA can directly code for the synthesis of proteins, hence can easily express the characters. DNA, however, is dependent on RNA for synthesis of proteins. The protein synthesising machinery has evolved around RNA

RNA though is distributed throughout the cell, it is most commonly in these structures
