Question

1. Bearing in mind the different number of hydrogen bonds that form between the two different purine-pyrimidine pairs in DNA, how would you explain the fact that DNA that is rich in cytosine-guanine pairs requires heating to a slightly higher temperature in order to separate the strands than DNA that is rich in adenine-thymine pairs? 

DNA that is rich in cytosine-guanine pairs requires higher temperatures to separate because these pairs form three hydrogen bonds, which are stronger than the two hydrogen bonds formed by adenine-thymine pairs. This means that more energy is needed to break the bonds and separate the strands in DNA rich in cytosine-guanine pairs.
