Question

Why is DNA molecule more stable genetic material than RNA? Explain.

Explain

Solution

DNA lacks the reactive 2′-OH group found in RNA and contains thymine instead of the less-stable uracil. Its double-stranded complementary structure also supports accurate repair, making it more chemically and structurally stable.
