American scientist developed a kind of new technology a few days ago, can lock up the guilty suspect that decides a likelihood according to the DNA example of guilty spot thimbleful.
The use of DNA appraisal technology is in group of legal medical expert is more and more general, it can make police passes what stay on guilty suspicion person the circumstance such as the status that any small matter judgement give him, posture. technology of current legal medical expert, if be in jumbly DNA example, the DNA material that belongs a certain person is little at 10 ％ , decide the identity of this individual and case very hard.
The new-style DNA legal medical expert that scientist of American California university develops analyses a technology to make the accuracy of method of this one appraisal rises greatly. Although a few people will pass the spot, perhaps have 200 many DNA example is jumbly together, want to have 0 only. 1 ％ belongs a certain person, new technology can identify come out.
New technology is with " sex of much condition of odd nucleotide acid " technology of high density small array is developed for the foundation and become. According to the report, what the DNA that carries human body hereditary information differs by 4 is alkaline base combine and become, of group of different person gene alkaline base arrange ordinal much identical, but also put in dinky difference, this differentia different is called " sex of much condition of odd nucleotide acid " . Right " sex of much condition of odd nucleotide acid " detect the accuracy that can raise DNA to detect greatly.
The scientist points out, this kind of new technology can be helped handle a case personnel identifies guilty suspect identity and case quickly, and detect cost also under current technology.
