DNA is considered as a better genetic material because it is stable and does not change with age or change in physiology due to its double-stranded nature and presence of thymine. RNA is not considered as a better genetic material because (i) 2—-OH group of RNA nucleotide is a reactive group that make RNA labile and easily degradable. (ii) RNA (23S r-RNA) is catalytic, i.e. it is reactive.
Why is DNA considered a better hereditary material than RNA?
