Given: The compound(s), which on reaction with \( \text{HNO}_3 \) will give the product having degree of rotation, \( [\alpha]_D = -52.7^\circ \), is(are):
For a double strand DNA, one strand is given below: The amount of energy required to split the double strand DNA into two single strands is _____ \( \text{kcal mol}^{-1} \). [Given: Average energy per H-bond for A–T base pair = \( 1.0 \, \text{kcal mol}^{-1} \), G–C base pair = \( 1.5 \, \text{kcal mol}^{-1} \), and A–U base pair = \( 1.25 \, \text{kcal mol}^{-1} \). Ignore repulsion between the phosphate groups.]
