Make some predictions about how primer length and GC content affect primer \( T_{\mathrm{m}} \). Q3.11. How will \( \boldsymbol{T}_{\mathbf{m}} \) change as GC content increases? (Hint: Recall the difference in number of hydrogen bonds between GC and AT base pairs.) Increase - Decrease No change Q3.12. How will \( T_{\mathrm{m}} \) change as the primer length increases? Increase Decrease No change
