For DNA,a Plot of the Change in Absorbance Versus Temperature

question 15

Multiple Choice

For DNA,a plot of the change in absorbance versus temperature would be ________,which indicates ________.

• A)hyperbolic;a simple equilibrium between the native conformation and denatured DNA
• B)linear;the breaking of bonds between the base pairs is an independent process
• C)variable in shape (hyperbolic,linear or sigmoidal);the dependence of the denaturing process on the sequence of the DNA
• D)sigmoidal;cooperativity where disruptions in the base stacking at one position destabilizes the stacking in neighboring base pairs
