Answer #1

Answer:

B). A/T base pairs

Explanation:

Guanine pairs with Cytosine with three hydrogen bonds whereas adenine pairs with thymine with two hydrogen bonds. To break two hydrogen bonds is easy to unwind DNA. So it is easiest to unwind DNA at regions that contain a log A/T base pairs.

    1. Very simple toy model for base-pairing of double stranded DNA. (This problem is originally due to Kittel.) DNA is an important biological heteropolymer. A single DNA molecule base-pairs with a complementary DNA molecule to form a duplex double stranded structure. Consider two strands of complementary DNA. Each strand has N monomers. Each monomer is cross- linked by base-pairing to the corresponding monomer on the complementary DNA molecule. Suppose that the energy for breaking a cross link is є and...
