Question

Identify the correct statements from the following. I) When DNA is hydrolysed adenine and thymine are obtained in equal quantities. 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. (A) I,II,III only (B) I, II, III, IV (C) I, II, IV only (D) I, IV only

Tardigrade Admin · Accepted Answer

Statements I and IV are correct statements.

I. When DNA is hydrolysed adenine and thymine are obtained in equal quantities because these two are bonded by H-bonds.

II. When RNA is hydrolysed, adenine and uracil are obtained in unequal quantities.

III. Amylose is an unbranched polymer with

200 - 1000 α - D (+)

- glucose units that are held together by

C_{1} - C_{4}

glycosidic linkage.

IV. Addison's disease is due to the abnormal functioning of adrenal cortex. It is caused by deficiency of minerals corticoids.
