21．（6分）It's hair-raising news for criminals on the run. Scientists behind a new study have worked out how to identify individuals only based on the proteins(蛋白质) in a single strand of their hair.While the police already look at DNA from hair as part of investigations, the technique is far from ideal: DNA is easily degradable, meaning it can only be analyzed within a certain time period after the crime. But the new technique could even be used to solve historical or archaeological cases, making it far superior to DNA sequencing in many ways.DNA degradation depends on several environmental factors including temperature, humidity and PH. It is also affected by the activity of bacteria and other microorganisms. In contrast, actual hairs can survive for a long time-----sometimes centuries. After bones and teeth, hair is in fact one of the most resistant structures of the human body.In order to understand how the protein can be used to identify individuals, it is important to understand mat proteins are coded by DNA．This means that a certain level of the genetic variation that we see in different people's DNA passes into their proteins. In fact, genetic information in the DNA is translated into amino-acid chains that make up proteins.The method not only allows for human identification but it can also reveal how old the sample is and what region it comes from, so that we can distinguish between current and ancient samples. But while the discovery is exciting, the technique is not quite polished enough to be used in the court room. The m。
