共用题干第二篇DNA FingerprintingDNA is the genetic material found within the cell nuclei of all living things. In mammals(哺乳动物) the strands of DNA are grouped into structures called chromosomes(染色体).With the exception of identicaltwins,the complete DNA of each individual is unique.DNA fingerprinting is sometimes called DNA typing. It is a method of identification that compares bits of DNA.A DAN fingerprint is constructed by first drawing out a DNA sample from body tissue or fluid such as hair , blood,or saliva(唾液).The sample is then segmented using enzymes(酶),and the segments are arranged by size.The segments are marked with probes and exposed on X-ray film,where they form a pat- tern of black bars一the DNA fingerprint.If the DNA fingerprints produced from two different samples match, the two samples probably came from the same person.DNA fingerprinting was first developed as an identification technique in 1985.Originally used to detect the presence of genetic diseases,it soon came to be used in criminal investigations and legal affairs.The first criminal conviction based on DNA evidence in the United States occurred in 1988.In criminal investiga- tions,DNA fingerprints derived from evidence collected at the crime scene are compared to the DNA finger- prints of suspects.Generally,courts have accepted the reliability of DNA testing and admitted DNA test re- sults into evidence.However,DNA fingerprinting is controversial in a number of areas:the accuracy of the results,the cost of testing,and the possible misuse of the technique.The accuracy of DNA fingerprinting has been challenged for several reasons. First,because DNA segmentsrather than complete DNA strands are"fingerprinted";a DNA fingerprint may not be unique;large-scale research to confirm the uniqueness of DNA fingerprinting.test results has not been conducted.In addition, DNA fingerprinting is often done in private laboratories that may not follow uniform testing standards and quality controls.Also,since human beings must interpret the test,human error could lead to false results.DNA fingerprinting is expensive.Suspects who are unable to provide their own DNA to experts may not be able to successfully defend themselves against charges based on DNA evidence.Widespread use of DNA testing for identification purposes may lead to the establishment of a DNA fingerprint database.People question the reliability of DNA fingerprinting for________.A:the subjective interpretation of test resultsB:its complex procedureC:its large scale researchD:its uniform testing standards
