WebThe authors reported the apparent hypochromities of 3 to 16% for many kinds of mixtures of the models and DNA or RNA, as compiled in Table 1. However, for the mixtures APVA + RNA, HPVA + RNA HPVA + DNA, THPVA + RNA, CPVA + DNA and CPVA + RNA, no hypochromicity was detected. [Pg.137] Table 1. WebWhen DNA is denatured, why does absorbance increase at 260 nm? DNA denaturation hyperchromicity The bases become unstacked and thus absorb more light. The bases of DNA absorb light in the 260-nm wavelength region in their native state. The striking increase in DNA absorbance after denaturation is known as the hyperchromic effect. cheffins at the beaumont inn

"WebThis can also confirmed by the lower hyperchromicity value, seen in appendix 1. As hyperchromicity is the measure of DNA denaturation (Pelley, 2012), the lower hyperchromicity value means that less DNA has been denatured, leading to the belief that more G-C is present and needs a higher temperature to be denatured.

Heat denaturation of DNA, also called melting, causes the double helix structure to unwind to form single stranded DNA. When DNA in solution is heated above its melting temperature (usually more than 80 °C), the double-stranded DNA unwinds to form single-stranded DNA.
