DNA is something like hair or finger prints, it makes it easier to find the suspect because only one person in the world can have a specific pattern on their finger. Even twins have different ones. Hair can be very different to someone elses. The more clues that direct to one suspect make it easier to find the truth.

∙ 14y agoDNA evidence (bodily excretions, hair, or skin) collected at a crime scene is compared with samples collected from the suspect/defendant and scientifically processed one against the other to determine if they match. It is scientifically proven that the odds of two people having the same DNA profile is 100's of millions to one.

∙ 13y agoThe DNA (Deoxyribonucleic acid) of each individual is distinctly different from that of every other person. As DNA is present in every cell of the human body, and the cells are shedded continuously from the skin, DNA found at a crime scene may originate from a suspect. DNA tests and the comparison of the results can then determine of the DNA is from the suspect or not, and is strong forensic evidence in court - so long as the DNA was found on, ie. a murder weapon, or the victim themselves.

∙ 13y agoEach persons DNA is different... even twins. When you put DNA in a HPLC you will be able to find the certain characteristics of DNA and match it to any persons DNA you already have in your system.
When using chromatography you have computer software. In that software you can keep a library of certain samples. Lets say you have a criminal and you have his DNA. Lets say he commits a crime and you need to prove that he did it. Well you can match the DNA from the crime scene that is his and put it through the HPLC. The HPLC will then match the crime scene DNA with the DNA you have stored in your software.

What are the aspect of biotechnology has been used to clear innocent people of crimes they were accused of committing?
DNA
How is biotechnology used to solve crimes?
DNA evidence can help convict criminals or show that an accused person is innocent.
What helps to solve crimes because no two people have the same DNA except identical twins?
If there is DNA at a crimescene, you can connect it to a persons DNA.
Why is DNA important?
DNA is like the "blue prints" of a person. Almost everything that happens in your body is based on DNA. It could be used to identify people. It could be used to find out if someone is someone's child, parent or other relative. It is often used to solve crimes. A hair or blood found on the crime scene could match the DNA sample of a suspect who is claiming he's never been at the scene. It could also be used to find genetic diseases.

How is DNA fingerprints used to solve crimes?
DNA fingerprints are used in forensic investigations to link suspects to a crime scene or to eliminate suspects. By comparing the unique patterns of DNA found at a crime scene to those of potential suspects, forensic analysts can establish if there is a match, helping to identify or rule out individuals involved in the crime. This scientific method provides strong evidence for solving crimes and is a valuable tool in the criminal justice system.
How is chromatography used in DNA mapping to identify a criminal in a murder case?
Chromatography is an important tool in DNA mapping. It can be used to match any DNA to previous DNA that is already on record from other crimes.

How can DNA solve crimes?
It can be used to identify the criminals easily if the criminal's hair sample or blood sample is collected and comparing it with the DNA of the suspects

yes

What percent of crimes are solved by DNA?
over 9000
What is DNA information used for?
There are many various uses for the DNA in the modern world. For example, DNA is used to solve crimes, in the paternity and maternity tests, and in the medical and genetic research. The basic principal is that any living organism has individual DNA pattern that's unique and proprietary to them. There are exceptions to this rule, identical twins for example have identical DNA.
In what type of real life situation would the extraction of DNA be useful?
Stem cells in general benefit from being injected with DNA. DNA is used in many crimes to determine who is guilty. For instance, a rape victimcould have skin underneath her fingernails that could be used to identify the perpetrator.

Do police DNA test in California for low costing crimes?
Yes
