Why is DNA a better genetic material when compared to RNA?

1.	Why is DNA a better genetic material when compared to RNA?
Answer» DNA is a better genetic material for the following reasons: (i) The genetic material should be stable and should not change with age or change in physiology; this stability is given to DNA by its (b) Double stranded nature, (c) Presence of thymine. (ii) Because the 2'- OH group of RNA nucleotid3es is a reactive group that makes RNA labile and easily degradable . (iii) RNA (23S RNA) is also catalytic, i.e., it is reactive.
