Best Answer: Melting point of DNA is related to the GC content of it. Since GC forms three hydrogen bonds, while AT forms two hydrogen bonds, the more GC you have in your DNA the higher the melting point will be.If the GC content is about 50%, the melting point is around 50C.The exact number is hard to calculate and there really isn't a universally accepted way of calculating melting temp base on the sequence. You can monitor DNA melting through UV light.f the GC content is about 50%, the melting point is around 50C.

(Redirected from DNA melting). Nucleic acid thermodynamics is the study of how temperature affects the nucleic acid structure of double-stranded DNA (dsDNA). The melting temperature (Tm) is defined as the temperature at which half of the DNA strands are in the random coil or single-stranded (ssDNA) state.Tm depends on the length of the DNA molecule and its specific nucleotide sequence.he melting temperature, T m, occurs when half of the double-stranded nucleic acid has dissociated. If no additional nucleic acids are present, then [A], [B], and [AB] will be equal, and equal to half the initial concentration of double-stranded nucleic acid, [AB] initial.
