dna matches?

Question

like if dna was found at a crime scene and the police ran it through the computers would they 100% be likely to find the person it belongs to? or would it only search through registered criminals?

and i swear i did not commit a crime!!!

Answer 1

First, they have the DNA at the crime scene. Then they need the DNA that matches. If they have it on file, that's easy. But if not, if the person has not yet been typed, then they will wait until they have a suspect in custody and do the testing, looking for a match. So it is as likely to free a person falsely accused as it is to convict the guilty.

Answer 2

Actually, the US government (gotta love em), has passed laws now stating that DNA will be taken from all registered sex offenders (I agree with that one), all felony offenders (ummm...maybe getting a little off base here) and now, in several states, you will be required to hand over a cheek swab just for being arrested - NOT convicted of ANYTHING. The goal is to have the DNA of all Americans in CODIS (the Combined DNA Index System) which is the FBI's computer system. Then, you better be careful if you are out in public and you sneeze. If a murder happens there later - you could be in some major trouble. I just did a huge paper on this for school and I was really shocked at the info I found.

As for DNA matching - several medical companies, including a Kaiser Permanente in CA and Children's Hospital in PA, are starting to DNA type their patients for genetic testing. So, technically, if you aren't a criminal - you may be safe for now....but not for long :)

Well they would at least need a suspect and get their dna to run through a gel electrolyosis and match it with the dna that they found at a crime scene. They might know how you look like, how tall you are or what type blood you have, but they would need your dna inorder to get a 100 percent match. I think the odds that 2 of the same people having the same match is 1 out of several billion.

Answer 4

Well, a very good question... The DNA of only the criminals or the people suspected of crime (whose DNA is collected) will be detected by the computer..... This is called DNA fingerprinting and is a very useful 'key' in Forensic crime detection.
Its not possible to record or collect entire worlds DNA by the police, as its a cumbersome and may not yield to benefit in an open and shut case.

Answer 5

I think that it would go thru registered criminals but also people in the military and those who work in government service jobs.
it is not likely that they would find you if you were never fingerprinted....when the police find the dna at the crime scene, that is only half the battle. the second part of it is to find the match.
If they have no idea who the suspects are it is unlikey that that match will be found if that person does not commit another crime where he is apprehended and finger printed.

Answer 6

DNA has the comparable form of sequences interior the Ape because it does interior the human however the adaptation is that categorical sequences at the instant are not became on which aspects the distinguishing features of the quite a few species. Even the blow fish has the comparable form of sequences as someone. Researchers used the blow fish to % out vast quantities of human DNA sequences because of the fact the blow fish has a lots smaller form of the sequences became on making it extra handy to % out what each sequence did. it is how evolution works. The blow fish might have been hit with intense radiation or poisoned by chemical compounds inflicting mutations (permitting DNA sequences to be became on) to take place (probable limbs and lungs with the aid of duplicate) permitting the newly born blow fish to go away the water for land. many situations the mutations are undesirable inflicting untimely demise yet very equivalent to the flu (poisoned by human antibiotics), it may reason the recent tension to thrive. We see those mutations in nature continuously jointly with a frog with 2 heads, a human with 8 limbs, or a sparkling virus it is proof against antibiotics.

Answer 7

It will search through a DNA database from those people who they have gotten DNA samples from, not only registered criminals.

Answer 8

I dont know if the police have a dna bank like they do fingerprints, but if they do you probably sould have had to previously done something for them to have your dna. so no they wouldnt have everone and therefore wouldt be 100% likely to find them if they can/could? run it through computers and if they find dna evidence they usually have a couple of suspects and will obtain dna from them so they can try and find a match

Answer 9

only register people and NO they dont have to be criminals. as long as they are in the computer log they're out of luck haha
