Complete hydrolysis of DNA does not yield
- A Phosphoric acid
- B Pentose sugar
- C Nitrogen containing compound
- D Secondary alcohol
Answer & Solution
Correct Answer
(D) Secondary alcohol
Step-by-step Solution
Detailed explanation
The complete hydrolysis of DNA yields phosphoric acid, a pentose sugar (deoxyribose), and nitrogen-containing compounds (nitrogenous bases). Deoxyribose contains hydroxyl groups, including a secondary alcohol group at C3 and a primary alcohol group at C5. However, "secondary…
