What are the hydrolysis products of the following ? DNA containing Thymine
Show Hint
Solution and Explanation
• DNA (Deoxyribonucleic acid) is a polymer made of nucleotide monomers.
• Each nucleotide consists of a phosphate group, a pentose sugar, and a nitrogenous base.
• Complete hydrolysis breaks all the phosphodiester and N-glycosidic bonds.
Step 1: Identify the sugar component
DNA contains a specific five-carbon sugar known as 2-deoxy-D-ribose. Unlike RNA, it lacks a hydroxyl group at the second carbon position.
Step 2: Identify the acidic component
The backbone of DNA consists of phosphate groups that link the sugars. Complete hydrolysis of these linkages yields phosphoric acid (\( H_{3}PO_{4} \)).
Step 3: Identify the nitrogenous bases
DNA contains four heterocyclic bases. For the specific case mentioned: - Purines: Adenine (A) and Guanine (G) - Pyrimidines: Cytosine (C) and Thymine (T)
Thymine is the base characteristic of DNA; in RNA, it is replaced by Uracil. The final answer is Deoxyribose, Phosphoric acid, and nitrogenous bases (A, G, C, T).
