How DNA is the better genetic material than RNA. Mention an organism with RNA as genetic material.

Explanation

1) The 2-OH group present at every nucleotide in RNA is reactive and makes RNA labile and degradable. But, DNA is less reactive and structurally more stable.
2) The presence of Thymine in place of Uracil in DNA confers its additional stability.
3) RNA being unstable, mutate at a faster rate but DNA provide scope for slow changes (mutation) that are required for evolution.
