what is DNA, what is it used for and how can this information be useful to a forensic scientist?

Simply DNA is an organic computer program which contains all of the information to grow an organic creature, such as mice, worms and humans.\n\nDNA is all but as individual as you are, so DNA can be used by forensic scientists to narrow down the search for the perp in a murder enquiry.\n\nDNA (if read) can provide much information:\n\napproximate height, hair colour, ethnicity, eye colour, approximate age, etc...

Forensic science is analyzing the physical evidence to link a suspect to a crime. Criminology is studying why a person, the motives involved, would commit a crime.

Check out the web links below. I think the answers to your questions are there.\n\nForensic science technicians investigate crimes by collecting and analyzing physical evidence. Often, they specialize in areas such as DNA analysis or firearm examination, performing tests on weapons or on substances such as fiber, glass, hair, tissue, and body fluids to determine their significance to the investigation. Proper collection and storage methods are important to protect the evidence. Forensic science technicians also prepare reports to document their findings and the laboratory techniques used, and they may provide information and expert opinion to investigators. When criminal cases come to trial, forensic science technicians often give testimony, as expert witnesses, on specific laboratory findings by identifying and classifying substances, materials, and other evidence collected at the scene of a crime. Some forensic science technicians work closely with other experts or technicians. For example, a forensic science technician may consult either a medical expert about the exact time and cause of a death or a technician who specializes in DNA typing in hopes of matching a DNA type to a suspect.

DNA tells your cells what to do and how to do it. it is the reason I have blue eyes and brown hair. It's the reason I love chocolate and can't stand brussel sprouts. The chromosomes of DNA are, as said before, like blueprints. That is why DNA plays a major role in the human body.

i think that anytime you do anything you should have both your fingerprint and DNA recorded, the bigger the database the larger chance of criminals being caught. even for little things like traffic tickets - at least that way there is a real database. The only people who can be caught are those whose DNA is already on record; or the police have to go and get the DNA. That would bring in the whole: Do they really need to take my DNA for a parking ticket but  the general populace should have nothing to fear - unless they are planning to do something wrong. It would just make us safer and better able to put the right people behind bars.

In criminal cases, this generally involves obtaining samples from crime-scene evidence and a suspect, extracting the DNA, and analyzing it for the presence of a set of specific DNA regions (markers).\n\nScientists find the markers in a DNA sample by designing small pieces of DNA (probes) that will each seek out and bind to a complementary DNA sequence in the sample. A series of probes bound to a DNA sample creates a distinctive pattern for an individual. Forensic scientists compare these DNA profiles to determine whether the suspect's sample matches the evidence sample. A marker by itself usually is not unique to an individual; if, however, two DNA samples are alike at four or five regions, odds are great that the samples are from the same person.\n\nIf the sample profiles don't match, the person did not contribute the DNA at the crime scene.

Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. DNA is a long polymer of nucleotides and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides\n\nhttp://en.wikipedia.org/wiki/Dna

Scientists in labs test blood samples (with chemistry) and other specimen from the crime scene to help find suspects. For example, they might test a paint chip from the crime scene with chemicals to see if it reacts, then test a car with what looks like matching paint to see if the two samples of paint match, therefore finding a huge lead!\n\nAnd testing DNA, of course.

In many cases the so-called 'junk' DNA carried by many organisms is probably similar to the old wives' tale that we only use 10% of our brains.\n\nIt looks like a lot of DNA goes unused in the day to day operations of the cell and in the process of gene transcription, but this probably means we just don't know yet what it does, and not that it isn't needed.\n\nEverytime medical science has said that some organ or other is vestigial and serves no purpose, we soon find out that it really does have a function.  Not always a major role, or a vital function, but some function.  Usually this occurs sometime after the doctors have spent decades performing needless operations removing tonsils or appendixes willy nilly.\n\nIt seems likely that someday we'll find that a lot of that DNA really does serve a purpose.  Perhaps it is only switched on in special circumstances, or maybe it's something like a glossary that reminds the cell how the stuff in the rest of the DNA is supposed to be spelled, so that random errors can be corrected (or added to).  \n\nMaybe it really is useless, ancient data.  The genetic equivalent of our high school yearbooks or the address book from twenty years ago that's still stuck in the back of one desk drawer.  \n\nPerhaps it's material that the cell isn't using right now, but would be really valuable if we did.  Maybe it's like that cardboard box that goes through six moves without being opened, and so we finally open it, and HEY, COOL!!! LEGO!!!!

A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.\n\nETYMOLOGY: \nd(eoxyribo)n(ucleic) a(cid)

Fingerprints, DNA and other individual characteristics are unique to the individual. The police use these identifying characterisitics to match particular evidence found in a crime scene to an individual. Fingerprints for example are matched on 6-10 points of identification/reference leaving no room for doubt that the match is at least 99.9%.

Forensic science (often shortened to forensics) is the application of a broad spectrum of sciences to answer questions of interest to the legal system. This may be in relation to a crime or to a civil action. The use of the term "forensics" in place of "forensic science" could be considered incorrect; the term "forensic" is effectively a synonym for "legal" or "related to courts" (from Latin, it means "before the forum").
