II ) When RNA is hydrolysed, adenine and uracil are obtained in equal quantities. III ) Amylose is branched polymer with α 1 → 4 and α 1 → 6 glycosidic linkages. IV ) Addison disease is due to the abnormal functioning of adrenal cortex.
Options
- AI ,   II ,   III only
- BI ,   II ,   III ,   IV
- CI ,   II ,   IV   only
- DI ,   IV only
Correct answer
D. I ,   IV only
Step-by-step solution
1. When DNA is hydrolysed, adenine and thymine are obtained in equal quantities. 2. When RNA is hydrolysed, adenine and uracil are not obtained in equal quantities. 3. Amylose only gas 1 → 4 glycosidic linkage. 4. Addison disease is due to the abnormal functioning of adrenal cortex.
