article_snippet.sent: Dr Graham Williams, who leads the Forensic Genetics Research Group at Huddersfield, alongside Leander Stewart and the Forensic Genetics Research Group colleagues have now come up with a method which could solve such riddles.
article_snippet.sent: Dr Graham Williams (pictured), who leads the Forensic Genetics Research Group at Huddersfield, found that by heating DNA until the Forensic Genetics Research Group bonds break these subtle differences become apparent. 
article_snippet.sent: The technique is based on the concept of DNA methylation - the molecular mechanism that turns various genes on and off .
