WebTools. Melting curve analysis is an assessment of the dissociation characteristics of double-stranded DNA during heating. As the temperature is raised, the double strand begins to dissociate leading to a rise in the absorbance intensity, hyperchromicity. The temperature at which 50% of DNA is denatured is known as the melting temperature. Webtime is called a heating curve. Let's look at the heating curve for water. Heating Curves Notice that, in general, the temperature goes up the longer the heating continues. However, there are two horizontal flat parts (segments BC and DE) to the graph. These happen when there is a change of state. The plateaus are also called phase changes. kylie birthday collection https://prideandjoyinvestments.com
