DNA samples are taken from the suspects and the victims at the crime scene. PCR is used to amplify the quantity of DNA and restriction enzymes are used to cut them. These DNA fragments are then placed between electrodes for the process of electrophoresis, where the application of an electric field causes the fragments to separate according to their sizes. DNA profiles are created as a result. Comparison is made between the banding patterns to identify criminals and victims.
Well here is several.
Applications of DNA fingerprinting and Forensic Science:
a). convict a suspect
b.) exonerate a convict
c.) identify crime victims
d.) prove paternity
e.) seek family lineage
f.) study plant, human and animal fossils
g.) seek the origin of nonhuman materials (ex. caviar origin)
h.) protect endangered species (by proving the origin of contraband animal products).
DNA profiling is used for many reasons. Some of these include: establishing paternity , identifying siblings, and helping to solve crimes.
DNA fingerprinting can be used to trace a criminal and it is also used to work out the biological parents of an orphaned child.
if a manner of death has been identified what is the next steps for an ivestigaton
i can be used since its legal but many may argue that its a infiltration of personality and that it should be banned.on the other side it is very helpfull when identifying people
when your friend want to know who is you and when your friend have interest to you
DNA profiling is used in forensic cases and paternity cases.
Parentage verification and id of a body or perpetrator in a forensics case.
The most likely technique they use is DNA profiling, where short tandem repeats (STRs) are compared from the DNA obtained from the finger prints.
phenol is used in order to remove protein impurities from the DNA to yield pure dna while chloroform prevents shearing of DNA during isolation.
In biochemistry, intercalator is a type of molecule that binds to DNA and inserts itself into the DNA structure. Some intercalators are used as treatments for cancer.
This step is used to danature DNA (separate two strands) by NaOH: Denature the DNA by adding freshly prepared NaOH (3 M) to a final concentration of 0.3 M. Incubate at 42°C for 30 min.
Loading dye is a substance commonly used in labs and the study of genetics. It causes DNA to become clearer under a microscope by tinting it purple.
DNA profiling is used by forensic experts to identify an individual. This technique is mostly used for parental testing and crime investigation.

Another thing is to look for genetic damage or change in chromosome number which can lead to birth defects.
DNA profiling proved that we share 98% of our DNA with primates.
DNA profiling is a technique employed by forensic scientists to assist in the identification of individuals on the basis of their respective DNA profiles.

DNA fingerprinting is not as reliable as regular DNA profiling. Statistics show that about one out every 800,000 people have the same DNA fingerprint.
The most likely technique they use is DNA profiling, where short tandem repeats (STRs) are compared from the DNA obtained from the finger prints.
The DNA in the nucleus, although this would need to be a white blood cell as red blood cells have no nucleus, instead using the space to store oxygen.
DNA profiling
According to Answers.com DNA profiling was developed in 1984 by British geneticist Sir Alec Jeffreys, and first used in forensic science to convict Colin Pitchfork in the 1988 Enderby murders case. http://www.answers.com/DNA
