DNA melting curves are the basis of several experimental and clinical techniques. High-resolution melting (HRM) analysis uses melting curves to measure features of DNA oligos such as differences in sequence, purity of PCR products, or even methylation state. A thermal denaturation experiment determines the stability of the secondary structure of a DNA or RNA and aids in the choice of the sequences for antisense oligomers or PCR primers. Beyond a simple numerical value (the T(m)), a thermal denaturation experiment, in which the folded fraction of a structure is plotted vs.

Beyond a simple numerical value (the T(m)), a thermal denaturation experiment, in which the folded fraction of a structure is plotted vs. temperature, yields important thermodynamic information.

the charged sugar-phosphate backbone. There are two basic approaches to denaturing double-stranded DNA. The figure below shows the denaturation curves for three DNA samples. Move the labels on the right to their appropriate targets on the curves. Then answer the two questions below.

each DNA sample is sheared to random fragments 500 bp long. Each DNA sample is at the same DNA (50 ug/ml) and NaCl concentration(1M).

Denaturation: The process of formation of single stranded DNA from double stranded helical DNA upon heating. Renaturation: The process of formation of double stranded DNA (reannealing) from single stranded DNA upon cooling. •DNA denaturation is the process of breaking down the DNA molecule, generally for the purposes of comparison or sequencing. opposite of the denaturation curve.

During the thermal denaturation of the sample the intensity of this absorption increases significantly to a maximum value. Monitoring the intensity of this peak throughout the denaturation gives rise to a DNA melt curve from which it is possible to determine the actual melt temperature and hence, calculate the The heat denaturation of DNA, also called melting, can be monitored experimentally by observing the absorption of ultraviolet light. The bases absorb light in the 260-nm-wavelength region.

Overview: The DNA Melting Algorithm. MeltSim is a statistical-mechanical program for calculating melting (denaturation) curves (derivative profiles) and maps of DNA, from genes to genomes. The model is the one-dimensional Ising lattice to which loop entropy has been appended [1] [2] [3]. The original algorithm is that of Poland & Scheraga [4] and Poland [5], with the Fixman & Friere approximation of the loop entropy by a sum of exponentials [6].

G:C base pairs contribute more to the stability of DNA than do A:T base pairs because of the greater number of hydrogen bonds for the former but (normally denaturation accomplished by heating a DNA solution ).
