WebJan 1, 2006 · INTRODUCTION. Stability of the DNA double helix with respect to separation of complementary strands is known to depend on the base composition of the duplex ( 1 – 4).A classical study of Marmur and Doty ( 1) on DNA polymer stability gives a linear relationship between the G•C content of the polymer and its melting temperature.The … WebMay 4, 2024 · 5. You're on the right track - when biologists say DNA "melts" they mean it denatures. Since DNA is a single molecule (okay, two connected molecules), albeit a large one, it doesn't really make sense to talk about its phase. Consider a single molecule of water: there's no way to tell whether that single molecule is a solid, liquid, or gas. pzi jeans at macy\u0027s https://hotelrestauranth.com
