Question

Chemically, RNA is (i)_____ reactive and (ii)_____ stable as compared to DNA.

Answer 1

Answer:

(i)more , (ii)less

Explanation:

2OH group present in ribose sugar of every nucleaotide of RNA is a reactive group. Uracil present in RNA is less stable as compared to thymine (= methyl uracil) of DNA. Being unstable, RNA mutates at a much faster rate and there is no repairing system.Consequently, viruses having RNA genome and having shorter life span mutate and evolve faster.

Answer 2

Answer:

(i)more , (ii)less
