(A): All DNA and RNA molecules contain adenine, guanine and cytosine base molecules (R): Adenine, guanine and cytosine molecules are examples of the same base type

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 equantities . III. Amylose is branched polymer with alpha 1 to 4 and alpha 1 to 6 glycosidic linkages. IV. Addison disease is due to the abnormal functioning of adrenal cortex .

The equivalent weight of a species if acts as oxidant or reductant should be derived by: Eq. weight Mol.wt. of oxidant or reductant = ("Mol.w.t of oxidant or reductant")/("Number of electrons lost or gained by onemclecule of oxidant or reductant") . During chemical reactions, equal all equivalents of one species react with same number of equivalents of other species giving same number of equivalent of products. However this is not true for reactants if they react in terms of moles. Also Molarity can be converted to normality by multiplying the molarity with valence factor or .n. factor The equivalent weight of an element is 13.16. It forms an acidic oxide which with KOH forms a salt isomorphous with K_(2)SO_4 The atomic weight of element is :
