Question

it's about dna fingerprinting its use & application in solving crime scenes...... suggest a gud site or any books???? ;-)

Answer 1

**This is a really easy readable site with simple words that are easy to change into your own so you will not be accused of plagiarism. ( copying someone else's idea's word for word. )

**Maybe this site will help, i am personally NOT familiar with this one, but i am familiar with the others... this one involves crime solving so hopefully it will help a lil bit??

** This is kinda, uhhh, a like ' you try it out yourself' site... i believe they give you scenerios and you need to gather facts and figure out basically who did it...lol, it seems pretty cool to me... but who knows, maybe we have totally different taste...right?

GOOD LUCK ON THAT PROJECT, OK?? i will cross my fingers for an A+ for ya...lol

Answer 2

search for RFLP and RAPD...applications and uses can be found...

Answer 3

google it

Answer 4

en.wikipedia.org/wiki/Fingerprint

Wikipedia often has false info, because of the purely user input, but this page had alot of helpful information.

^_^

Answer 5

ask the librarian?  

Answer 6

DNA stands for Deoxyribonucleic Acid. It is the genetic material of a cell. DNA is can also be described as the blueprint of an organism.

How DNA Profiling Helps to Solve Crimes:

DNA profiling or fingerprinting 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.

A DNA fingerprint is the same for every cell, tissue and organ of a person. This DNA fingerprint cannot be altered by any known treatment.

It makes sense that DNA evidence has become such a powerful crime solving tool because no person's DNA fingerprint is the same except for identical twins. This means that DNA collected from a crime scene can either link a suspect to the evidence or eliminate them which is why accurate DNA fingerprinting is critical as a crime solving tool.

Crime victims can be identified through DNA from relatives, even when no body can be found. And when DNA evidence from one crime scene is compared with DNA evidence from another, those crime scenes can be linked to the same perpetrator (in the USA) through systems like CODIS (Combined DNA Index System), an electronic database of DNA profiles that can identify suspects.

HOW TO COLLECT A DNA EVIDENCE AT A CRIME SCENE:DNA evidence can be collected from virtually anywhere at a crime scene. DNA has helped solve many cases when imaginative investigators collected evidence from non-traditional sources:

A masked rapist was convicted of forced oral copulation when his victim's DNA fingerprint matched DNA evidence swabbed from him.

Many cases have been solved by DNA analysis of saliva on cigarette butts, postage stamps, rims of cups and glasses.

DNA analysis of a single hair found deep in the victim's throat provided a critical piece of evidence to solve the crime and apprehened the criminal.

How Does DNA Fingerprinting or Profiling Work?

The chemical structure of everyone's DNA is the same. The only difference between people is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence.

Using these sequences, every person could be identified solely by the sequence of their base pairs. Instead, scientists are able to use a shorter method due to repeating patterns in the DNA. These patterns do not, however, give an individual "fingerprint," but they are able to determine whether two DNA samples are from the same person, related people, or non-related people. This is called DNA fingerprinting or profiling.
