area of DNA‚ deoxyribonucleic acid‚ helping on scientific research and most importantly as a tool for solving crimes. Before the usage of DNA‚ people only had shreds of evidence on the crime which could be detected by the naked eye. However‚ with the development of DNA detection technology‚ the police can identify or get some indication about the malefactor by collecting pieces of evidence that were impotent before; for example‚ hair‚ fingerprints and even blood (Travis‚ 1998). However‚ DNA testing

Running Head: CRIMINAL TECHNOLOGY Criminal Technology from the Past into the Future CJ216: Computers‚ Technology and Criminal Justice Information Systems Professor Lally July 19‚ 2011 In the past‚ technology was not very advanced; there were not very much communication devices. But the police managed to respond the fastest way to emergency calls. As time has passed‚ technology advanced‚ so all the technology that we have now 20 years ago people did not know of its existence. That is

Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase support

Evidence is a big factor when anybody is trialed for doing something illegal. It is the difference between being accused of being guilty or innocent. In “Forensic: Evidence‚ Clues‚ and Investigation” by Andrea Campbell‚ forensic science is the most important type of evidence to present at a trial. According to the passage‚ in paragraph five‚ the rules of forensic evidence are how evidence can be presented in the courtroom. There are four types of evidence. The first type is testimony‚ other types

Audit Evidence This chapter deals with the types of evidence decisions auditors make‚ the evidence available to auditors‚ and the use of that evidence in performing audits. NATURE OF EVIDENCE • Evidence is any information used by the auditor to determine whether the information being audited is stated in accordance with the established criteria. • Evidence includes information that is highly persuasive‚ such as the auditor ’s count of marketable securities‚ and less persuasive information

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

crime‚ the student also must consider the many different types of crimes‚ from criminal homicide to crimes against property to crimes against justice. Each offense has unique elements to prove‚ different states of mind‚ and varying degrees of punishment. Your assignment this week is to answer the following questions: • Research two criminal cases involving two different types of crime. • Explain how the facts of the cases meet the definition of the crime In addition to understanding the five items

procedure for extracting DNA‚ collecting DNA samples‚ and to observe the physical characteristics of DNA Background: The wild strawberry is a diploid because it only has two sets of chromosomes. While the grocery store kind is an octoploidy because it has eight sets of chromosomes. The reason we chose the grocery store strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break down the cell walls making it easier to extract the DNA. We will be using a solution

DNA REPLICATION WHAT IS DNA? DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A)‚ Guanine (G)‚ Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose. THE PROCESS OF DNA REPLICATION How DNA replicates is quite a simple process. First‚ a DNA molecule is "unzipped". In other words‚ it
