DNA and identification of future

DNA and identification of futureUtilization of DNA testing it is becoming a challenge and a choice of international talks on this the 21st century, when the validity of the conventional identity (blood type, identity cards, passports, facial expressions, a collection of personal photographs, fingerprints) are sometimes no longer effective. Among other catastrophic, such as tsunamis, often devastated human relationships and family. In this case, DNA testing offers an effective solution to regroup his family who had scattered. Here we see the contents of the new DNA.
The uniqueness of DNASince made clear by James Watson and Francis Crick April 1953, chromosomes or DNA into macromolecular chemistry is most famous because the character-lowering substance (identity) of the parent to the next generation. In a normal human diploid cells, there are 46 chromosomes with a total length of 1 ñ 2 meters. In one millimeter chromosomes are 3000 - 4000 genes.
While the gene itself is nothing but pieces (fragments) of DNA double strand polymer composed of nucleotides. As the smallest unit of genes, each nucleotide consists of three components, one molecule of nitrogen base, a five carbon sugar molecule (deoxyribose) and one phosphate group. Molecular nitrogen bases adenine, thymine, guanine and cytosine DNA macromolecules up buildings, also the gene.
The composition of this base affects a person's genetic makeup is inherited from both parents and siblings. A strand of DNA is structured by a three-foot about three billion bases of each pair of molecules according to Chargaff rules (introduced by biochemist Erwin Chargaff in 1947). Analogues with the form of a ladder with three billion rungs. According to Chargaff, molecular nitrogen bases adenine (A) pairs with Thymine (T), while guanine (G) with Cytosine (C = cytosine). Molecular bases of this sequence, as well as nucleotide sequence, vary in each individual who is not blood related, except in identical twins one egg (monozygotic twins).
Therefore, the pattern of nucleotide sequences in each strand of DNA is a biological personal identity (ID) is really specific to the uniqueness of an individual, at least in each of the three billion people in the world. Current world population is around 6.5 billion people. Set in the theory of random sampling, by taking a sample of 10 millimeters of chromosomes (one per cent of the total chromosome length), profile
NA already has a level of discrimination (specificity) for the individual among the 30 million inhabitants. Application, when tracked in the sample DNA profile evidence of a single perpetrator of crime cases in a population of 30 million, it is certain the individual is truly as the culprit.
Although no two individuals in the world with identical DNA, except identical twins. But in one family, each individual still has a similarity (a match) the pattern of molecular base pair sequence. Therefore, the sequence pattern is passed down from one generation to generation according to Mendelian genetic law. Hence, the DNA profile of a child is still possible indirectly identified from the birth parents or siblings through matching DNA profiles. Postulations raised this as an effective solution when there are suspected cases of babies swapped.
Identity as a permanent means of personal identity which remains attached to an individual even if a moment has passed. When the wide-open global mobility, the identity of permanent (perpetual) a person becomes increasingly crucial. Each individual has an opportunity to venture alone to the remote location in the corners of this planet. Even if by chance one day be found living skeleton in a location without any inhabitants, still allows DNA profiles to be identified. Future, and also now, when there is evidence of a match on the DNA profile with a brother or son, a tin of individual
gal framework is very likely ímenemukaní his family back for sure. Just to note, with the help of molecular DNA technology, genealogy can be identified and ídihidupkan pharaoh kembalií even been in a mummified condition.
Ethics of DNA RecordsIf the alphabet of four letters written by future molecular bases (A, T, G and C) for a single nucleotide, then a single gene can be placed quarter-page textbook. Therefore, when the 46 chromosomes of a i
individual to be fully written down on paper, it will spend 500 000 book-sized pages of text. Not able to save computer memory intact DNA profiles of every world's population now numbering 6.5 billion people.
There is the adage, seeing a bit of a chromosome, can be identified individuals

have a genetic biological curly-haired character, for example. But on the contrary, can be trapped in hyperbole, by examining a person's genes, can be obtained for certain information malignant tumor disease later in life journey in this world, except for genetic disorders. Something that is very privacy, in this case a person's DNA profile, risky to put into a computer database. Do not forget, only about one percent of the total length of human chromosomes commonly taken as a sample to identify the genetic character of a person.
Hope in the future, although the technology of DNA molecular complex and requires special equipment, with the computer databases of DNA profiles of the world population, are connected in a multinational, then the interstate crimes become easier to anticipate with a high degree of certainty. Leaving a trail of crime and trying to alibi to another country would not be interesting anymore. Because DNA is a reliable and highly effective identificator, when applied appropriately and accurately.
