RNA is less stable genetic material as compared to DNA. The reason for this is

Options

A. In RNA, 2' position has `-OH` group while DNA does not
B. RNA is also known to be catalytic
C. RNA has uracil while DNA has thymine
D. All of the above

Answer

D

Explanation

`**" "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 catalystic, hence reactive. Therefore, DNA chemically is less reactive and structurally more stable when compared to RNA.
`**" "`In fact, the presence of thymine at the place of uracil also confers additional stability to DNA.
