According to Newser.com report, scientists have found a new way to tell twins apart by studying the different melting points of their DNA.

According to Newser.com, identical twins have identical DNA that on time creates problems for crime scene investigators. There is a possibility that one could blame another for a crime or both could be suspects. As per Science Daily reports, the new method of processing DNA samples can help to find out one identical twin from another.

According to the scientists, they heat samples of DNA to their melting point or at that point at which the hydrogen bonds in our DNA break. The scientists said that every twin's DNA melts at a slightly different temperature. Lifestyle differences like smoking or exposure to sunlight can also cause such variances.

Newser.com reports that this new method is not foolproof as it needs a high-quality DNA sample. According to Dr. Graham Williams, the lead researcher, there is a possibility that crime-scene DNA evidence could not be sufficient quality.

This new technique needs a comparatively large sample, and it will not work if there's just a scant amount of DNA at a crime scene. But only few hours will be needed to get a result. According to Georgina Meakin of University College London, this new method is a step forward. Meakin said that twins who share the same habits and environment may have very few epigenetic differences.

As per experts, this might be a helpful tool when police look into one or both twins who are suspects in crime cases. The experts said that the present method for doing comparison of the DNA of identical twins accused of a crime is costly and is done in a month.
