The stages of DNA profiling are outlined and it is noted that DNA fingerprinting can provide strong evidence if a suspect's profile matches the biological evidence left at a crime scene.
Dna fingerprinting powerpoint
DNA profiling is a technique used by scientists to distinguish between individuals using samples of their DNA. Alec Jeffreys invented the process of DNA fingerprinting at the University of Leicester in 1985. The process involves extracting DNA from samples, cutting the DNA into fragments using restriction enzymes, separating the fragments by size using gel electrophoresis, and analyzing the pattern of fragment distribution to obtain a unique DNA profile. DNA profiling can be used to solve crimes by comparing DNA samples from a crime scene to suspects, and to solve medical problems like determining parentage in inheritance cases.
Dna profiling
This document provides an overview of DNA profiling and fingerprinting. It discusses how DNA was discovered to have a double helix structure, and how DNA fingerprinting works by analyzing variable regions of DNA to generate unique profiles. The document outlines the stages of DNA fingerprinting, from extracting DNA to generating bands patterns, and discusses applications like solving crimes, paternity testing, and identifying medical conditions. It provides an example of how DNA profiling can eliminate a suspect or link them to a crime scene.
Dna fingerprinting
DNA fingerprinting was developed in 1984 by Alec J. Jeffrey at the University of Leicester. It involves analyzing variable numbers of tandem repeats (VNTRs) in DNA to generate unique genetic profiles for identification purposes. DNA fingerprinting is now used for paternity testing, criminal investigations by comparing crime scene DNA to suspects' DNA, and identifying people or inherited health conditions through their DNA profile. While very accurate, DNA evidence requires careful analysis of potential random matches or errors and does not necessarily prove guilt on its own.

- 1. University of Puerto Rico<br />Cayey Campus<br />Jessica Díaz Rivera<br />Prof. Elena Gonzalez<br />Laboratory #5: DNA Profiling<br /> The laboratory that Dr. Belinda Roman gave was about DNA Profiling of how to solve a crime or medical problems. The objectives of the experiment was to resolve a crime, using DNA Profiling otherwise known as Forensic DNA Fingerprinting. DNA Profiling is a technique used by scientists to distinguish between individuals of the same species using only samples of their DNA. It is used to solve crime or medical problems. The DNA profile of each individual is highly specific. We did a PCR (Polymerase Chain Reaction) to amplify specific segments of DNA and electrophoresis gel to see DNA fragments. We had the crime scene samples as a positive control and the samples of suspects one to five. In the agarose gel electrophoresis we analyzed the different bands of DNA and compared them to the crime scene DNA. At the end, we concluded that the DNA from the crime scene was similar to the DNA of the third suspect. Therefore suspect number three was responsible for the crime. <br />
