Question
Which of the following characters provide additional stability to the structure of DNA?
(a) Absence of 2âOH in the pentose sugar
(b) Presence of thymine in place of uracil
(c) Presence of the phosphate group in the nucleotide
Easy
Solution
2'-OH group present in the sugar of every nucleotide in RNA is a reactive group and makes RNA labile and easily degradable. This 2' OH is absent in deoxyribose sugar of DNA. The presence of thymine at the place of uracil also confers additional stability to DNA.
