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. impacts of computer on societyWebHeat Capacity, Specific Heat Capacity, and a Heating Curve You know that it’s necessary to add heat to a substance to increase its temperature, but you might not know that it takes different amounts of heat energy to change the temperature of a specific amount of different substances by 1 degree Celsius. list three duties of the secretary of stateWebhttp://www.kentchemistry.com/links/Matter/HeatingCurve.htmI take you though the basics of interpreting a heating curve.
