30.Here are two pieces of DNA, one with an adenine plus thymine content of 40%, and the other with a cytosineplus guanine content of 50%. If both are heated under the same experimental conditions, which of thefollowing statement(s) about Tm of these DNAs is/are CORRECT?
(A) The DNA with 40% adenine plus thymine will have the higher Tm.
(B) The DNA with 50% adenine plus thymine will have the lower Tm.
(C) The DNA with 50% cytosine plus guanine will have the higher Tm.
(D) Their Tm's will be the same.
(E) There's no way to predict for this information.
