2. Q442024 · 26 May 2024 · Paper 2· Numerical answer

   For a double strand DNA, one strand is given below: $$5^{\prime }\text{A G T C A C G T A A G T C}{3}^{\prime }$$ The amount of energy required to split the double strand DNA into two single strands is ____ $\mathrm{kcal}\mathrm{mo}{\mathrm{l}}^{-1}$. [Given: Average energy per H-bond for A-T base pair = $1.0\mathrm{kcal}\mathrm{mo}{\mathrm{l}}^{-1}$, G-C base pair = $1.5\mathrm{kcal}\mathrm{mo}{\mathrm{l}}^{-1}$, and A-U base pair = $1.25\mathrm{kcal}\mathrm{mo}{\mathrm{l}}^{-1}$. Ignore electrostatic repulsion between the phosphate groups.]
