Тема: whats a good thesis for Dna Fingerprint 8th grade research paper please helpp?

DNA - or genetic - fingerprinting relies heavily on the principle that no two individuals share the same genetic code - except for identical twins and statistically those elements of DNA that are examined and used to obtain a match will be unique.

The process of DdnaNA fingerprinting was first used during the 1980's and its application was quickly to become that of identification of suspects involved in serious crimes including murder. The premise that most attackers or killers will leave some measure of bodily fluid at a crime scene - be it saliva, blood, semen or other such fluid - was quickly accepted as common place and it became a staple of many criminal investigations.

DNA fingerprinting is a test to identify and evaluate the genetic information-called DNA (deoxyribonucleic acid)-in a person's cells. It is called a "fingerprint" because it is very unlikely that any two people would have exactly the same DNA information, in the same way that it is very unlikely that any two people would have exactly the same physical fingerprint. The test is used to determine whether a family relationship exists between two people, to identify organisms causing a disease, and to solve crimes.

Only a small sample of cells is needed for DNA fingerprinting. A drop of blood or the root of a hair contains enough DNA for testing. Semen, hair , or skin scrapings are often used in criminal investigations .

The term DNA fingerprinting - or genetic fingerprinting - is applied to the scientific process whereby samples of DNA are collected, collated and used to match other samples of DNA, which may have been found at the scene of a crime.

Why Use DNA Fingerprinting? This process is used as one means of identification when an attacker or assailant has left some kind of bodily fluid or blood at the scene of a crime and when no visual identification is possible.

About 100 gm of muscle tissue should be sent in a clean glass bottle/plastic container with 0.9% DNS (normal saline sold in medical shops) on ice or in crystal salt (sodium chloride) as a preservative.
Tissue samples should not be preserved in formalin.

In the last 15 years, DNA has played an increasingly important role in our legal system. Tissue evidence is now routinely collected during criminal investigations in hopes that it will provide genetic clues linking suspected criminals to crimes.

DNA profiles help forensic investigators determine whether two tissue samples -- one from the crime scene and one from a suspect -- came from the same individual. Fortunately, the genetic comparison doesn t require that investigators look at all of the DNA found in the tissue samples. That would take months or even years. Instead, by marking a small number of segments of DNA in one sample and then checking for the presence or absence of those segments in the other sample, investigators can say with some assurance whether the samples are from the same person.

It's the case of the licked lollipop, and you have to solve it. Fortunately, you have the latest forensic technology on your side: DNA profiling. This interactive feature guides you through the process of creating DNA profiles of several criminal suspects and tissue evidence left at the crime scene. Then you'll compare the profiles you've created and, hopefully, find the criminal just like forensic investigators do. From NOVA: The Killer's Trail website.

Dna Fingerprinting Advantages And Disadvantages

DNA Fingerprinting History. It's the late 1970s and early 1980s and we're in the laboratory of Alec Jeffreys, the man who invented DNA fingerprinting.

Most dept's do fingerprints and then they are sent to the FBI for processing. Most dept's do not have AFIS machines (cost and eligibility). All evidence in my state is sent to regional forensic science dept's and it is all analized there and then the results are sent to the dept's. The process is usually lengthy, depending on urgency of the request, orders ahead of the request, staffing issues, and backlog. Most dept's do manual ink and paper fingerprints. (Cost) DNA, fibers, drug analysis, finger print analysis, etc would all be done by the dept of forensic science. I can't help but have a "CSI Effect" moment here. The process is lengthy, DNA takes 4-6 weeks on average to get back, drug analysis takes 2-6 weeks for analysis, nothing happens quickly and due to costs, most dept's do not have AFIS adn CODIS.
