3. Acids and bases. Guanine is weakly acidic. It can lose a proton at higher pH, which disrupts base pairing and DNA structure. (See section 1.3 of your textbook and the lecture slides.) $pK_a = 9.7$ A) Write the Henderson-Hasselbalch equation for the acid dissociation reaction of guanine. Identify the conjugate acid and conjugate base (HA and A-) for guanine forms. B) If the $pK_a = 9.7$ (see above), What is the value of the acid dissociation equilibrium $K_a$? C) At pH 7.4, calculate (1) the ratio of the protonated and deprotonated forms of guanine. (2) the fraction of protonated guanine (i.e., HA / (HA + A-) D) The titration curve above shows DNA being titrated with a strong base, such as NaOH. Calculate the precise fraction of DNA in the double helical form at three different pH values: 7.4, 8.4, and 9.4. [Hint: Note that the double-helical form requires the protonation of guanine. Therefore, you will need to calculate the fraction in part C (above).]

Example: 2. A compression helical spring is made from alloy steel wire of 5 mm diameter and has outside diameter of 80 mm . If the permissible shear stress is 375 MPa and modulus of rigidity \( 85 \mathrm{kN} / \mathrm{mm}^{2} \), determine the axial load which the spring can carry and the deflection per active turn.Take all the factors into account. Given : d \[ \begin{array}{ll} \mathrm{d} & =5 \mathrm{~mm} \\ \mathrm{D}_{0} & =80 \mathrm{~mm} \end{array} \]
