By measuring the UV-melting curves for the DNA of two different organisms (A and B) in the same solution and concentration, we have found the following melting temperatures (Tm): Tm(A)= 70.2 C and Tm(B)=75.6 C. Which of the following is correct? a. DNA molecule B requires less thermal energy to denaturate
