DNA profiling has been assuming a prominent role in the activities of the criminal justice system. Genetic technologies support criminal investigations, while also being seen as holding a highly valuable potential for producing evidence to be used in courts. This chapter has two main objectives: on...
Controversy erupted in the scientific community in early 1992 over the use of DNA (deoxyribonucleic acid)fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made...

in every cell of the body except red blood cells. dna fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. however, it is in the area of criminal investigations that dna fingerprinting has ...
DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA ...
In criminal investigations, DNA fingerprints derived from evidence collected at the crime scene are compared to the DNA fingerprints of suspects.Generally, courts have accepted the reliability of DNA testing and admitted DNA test results into evidence. However, DNA fingerprinting is controversial in a...

Use of DNA in Criminal Investigations Essay DNA forensics can also narrow down suspect pools, exonerate innocent suspects, and link crimes together if the same DNA is found at both scenes. However, without existing suspects, a DNA profile cannot direct an investigation because current knowledge of...
DNA（脱氧核糖核酸）是由核苷酸长链构成。核苷酸是由磷酸、戊糖核碱基组成。碱基有线嘌呤，鸟嘌呤、胞嘧啶、胸腺嘧啶4种，在每个核苷酸中只有1种碱基。DNA分子是由2条逆平行的多核苷酸长链围绕着一个中心轴盘旋转形成螺旋状结构，2 条多核苷酸链上的碱基严格按照互补（C—G、A—T）规律结合成对，结合...
