BASIS OF POLICE OF DNA INFORMATION PURPOSES CRIMINAL INVESTIGATION

Introduction

BASIS OF POLICE OF DNA INFORMATION PURPOSES CRIMINAL INVESTIGATION.

‘’DNA (deoxyribonucleic acid), a chemical component of the cell nucleus, is a personal code that only has an identifying feature, the only being that person. It is a genetic blueprint in the strictest sense.’’

is a serious issue to deal with, since we would involve them all, the use of personal information is serious to leave to collect your DNA that information would be in the hands of the police, I think this would affect in a negative way by taking the identity of a person seems to me that its integrity is violated, and well I do not think it would help much in resolving cases would cost too far?, increasing taxes would be visible..

EFECTIVENSES IN CRIMINAL PROCEEDINGS: Time For begin DNA expert evidence is the comparison between a-obtained undoubted of the suspect, or a bank dubitada-that shows that in principle it is not known what subject belongs, and other data-so that if the two match in their genetic markers, this form of evidence can serve the purpose of accreditation of judgment authoring with full guarantees, but such proof as any other, must have been obtained and provided to the proceedings with all guarantees required by the Constitution and our procedural laws .

The test takes an average of 5 calendar days from the time that all the samples are received in the laboratory until the results are reported.

At this time the attacker, criminal or whatever runaway change their nationality or something... I do not think it's very helpful…

Security LEGISLATIVE HISTORY

Seriously… every person with legislative history is a suspect, that’s no much intelligent.

the process could take twice as long from my point of view this would be a violation wing integrity of each person to be judged.

Genetic markers used in forensic genetics

There are two types of repeat polymorphisms in genetic diagnostic use , the VNTR - VNTR - minisatellites and microsatellites.

• The VNTR - minisatellites or MVR ( minisatellite variant repeats) are loci that correspond to DNA sequences of a few tens of nucleotides ( about 30 bp) repeated in tandem. The number of such repeats varies chromosome chromosome . The special feature of this type of polymorphisms uniqueness is that each loci may have many different alleles (as many repetitions ) , however have the drawback that they are not distributed throughout the genome and therefore can only be used in the diagnosis of a very small number of cases. The VNTR - minisatellites found its best application in the determination of paternity and genetic identification protocols in the judiciary . When talking about DNA fingerprinting is speaking of this kind of polymorphism .

• The VNTR - microsatellite or STR (short tandem repeats) correspond to the tandem repeat sequences 2 to 5 nucleotides. These markers have two characteristics that make them ideal for use. First, they are distributed almost evenly throughout the genome and secondly , they have a large number of alleles at similar frequencies to each other , so that the probability of an individual being heterozygous is extremely high ( have high heterozygosity ) .

These hypervariable regions belong to the so-called " antisense DNA " are non-conserved regions and thus not subject to strong selective pressure , causing a large number of variants , which are what we call alleles . These areas are called polymorphic which interest us in forensic genetics to differentiate from other samples . Therefore, it is not interesting to analyze the complete DNA molecule , mainly for two reasons :

• It would take a long time and

• Most of the molecule is common to all humans and could not be distinguished.

Interesting but the true is that security would have, generally of more than 99%

But more than interesting is what about this .. Every human being is different, two people may be more or less similar, especially between close relatives, but are never identical, except in the case of identical twins. This differentiation between people is that there are millions of possible combinations of DNA between an egg and a sperm, due to genetic recombination that occurs during meiosis. This is more than awesome… as might know a person who is to blame if the criminal has an identical twin?, in order not to speak of mutations in rare cases,well this is extreme and weird…

in order to take a long time and there may be exceptions with repect to prove a crime

To End: security

-Risk of Data Traffic by the very officials who have access to the DNA database. Following general maxims of experience knowledge can
