Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...
