DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you - unless you have an identical twin. Scientists today usually analyze DNA in blood, saliva （唾液）or hair left behind at the scene of a crime. The results often help detectives identify criminals and victims. Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cellphone and later dropped it. This made her wonder whether traces of DNA remained on cellphones - even when no blood was involved. To find out, she and a colleague collected flip-style （翻盖式）phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user’s ear. The scientists cleaned the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then they returned the phones and the researchers collected traces on each phone once more. They discovered DNA that belonged to the phone’s owner on each of the phones. Surprisingly, DNA was even picked up immediately after the phones were cleaned. That suggests that washing won’t remove all traces of evidence from a criminal’s cellphone. So cellphones can be added to the list of clues that can settle a crime-scene investigation. 64. In a crime-scene investigation, now experts are likely to turn to ________.
