Supplies the genetic fingerprint that looks much like a barcode comprised of millions of fragments of d.n.a. sequences. until recently only small amounts of such genetic information could be saved but now that's changed. now that computers have become so powerful we no longer have to choose just a few parts of a spectrum to save and discard the rest now we can save the entire spectrum. that's an enormous advantage now the chemist can store the genetic fingerprints of every sample when a new one arrives the computer can quickly identify similar or identical genetic fingerprints from its databas...

. shredded paper it's not dangerous but it's brazen fraud. at about eighteen euro's a gram it's not surprising they try this especially because as you've seen you can't detect the fake just by looking at it with other spices the fakes paying off because they're selling large quantities. most of the fraud can't be detected with the naked eye for that you need a chemical analysis until recently the chemists had to carry out a separate test for every compound and they had to know exactly what to look for but now. spectroscopy has changed that using this method single scan can provide a genetic pr...

Can last holding information holding a signal for more than half a million years. it took the german team nearly two weeks to decode all the d.n.a. sequences sent by the british research institute. all the d.n.a. strands would read and all the messages from be retrieved. to receive the sequence read information back from the heidelberg laboratory we decode those fragments of d.n.a. we put back together the binary files based on the information and then we want to compare whether that exactly matches what we started with the photograph looks exactly the same and we also checked in the computer ...

Made to me and i'm sure he will continue to fulfill that promise as they search. >> but identifying and returning the remains tend to be a challenging process, the biggest forensic anthropology lab in the world. first the remains are examined to determine features like sex, race and age of death, genealogists look at the soldier's family trees for possible dna samples, 99% of service members from korea have no dna record on file that forensic anthropologists will examine remnants such as military uniforms, belongings and identification tags. expert say teeth and bones could be the source of mi...

World. to come to the age of the german geneticists teamed up with wildlife biologists and conservationists the first stage involves looking for characteristic d.n.a. sequences that only occur in the genetic makeup of wild cats their aim was to assign individual has and all the tiny structures specifically to wild cats which proved complicated to. the heart and tightens the hair contains very little d.n.a. after a few days or a week in the forest that d.n.a. gradually degrades your soul was quite a challenge to capture valuable information from it special that i was for the whole god whole spi...
