Solution
The correct option is C Assertion is correct but Reason is incorrect
DNA is more stable while RNA is more reactive. It is because of the presence of the -OH group on the second carbon chain of the ribose sugar, which makes a ribonucleotide less stable than a deoxyribose molecule. The OH group makes it prone to the nucleophilic attack causing the breakage of a phosphodiester bond. DNA was first discovered by the scientist Friedrich Miescher was the first scientist who isolated Nucleic acid. The double helix model of DNA was given by Watson and Crick.So, the correct answer is option C.
