generation and the use of DNA information and analyses will contribute greatly to the field of criminal investigation and in effect‚ downgrade with expediency the crime rate in the country‚" Angara said. What are those for? DNA matching will become an ever more powerful weapon against crime. Law enforcement will increasingly be able to identify suspects from biological evidence at crime scenes‚ saving investigative time and protecting innocent people from suspicion. When DNA evidence is properly handled

Point mutation is an error at a particular point on the DNA molecule. Since the changes occur in DNA‚ in order to fix the mutation‚ scientists have to find out where something went wrong in the DNA structure and how to fix it. Technology improved and in recent years‚ we got new skills and we are able to change natural changes of DNA for our profit. It is still being worked on‚ but scientists can do a lot of impressing things with DNA structure now. Point mutations might initiate very dangerous changes

In order to understand the advantages and disadvantages of DNA profiling one must have a full understanding of what it is. DNA profiling‚ also referred to as DNA fingerprinting or genetic fingerprinting‚ is the process of identifying an individual by analyzing their DNA samples (body tissues‚ body fluids‚ bone‚ hair). This process did not exist until the mid-1980’s when English Scientist‚ Dr. Alec Jeffreys‚ discovered that DNA contains repetitive patterns that vary from individual to individual

Ethical Issues Involving DNA and Law Enforcement I. Introduction Beginning in the late 1980’s‚ the use of DNA has grown substantially in criminal justice systems around the globe. Like many other techniques that have been adopted by governments‚ DNA is a growing controversial issue. Proponents of the topic; mainly law enforcement agencies‚ claim that this scientific breakthrough can help identify suspects‚ exonerate the wrongly accused‚ and even prevent crime from happening in the future. Opponents

DNA DNA stands for deoxyribonucleic acid. DNA is part of our definition of a living organism. DNA is found in all living things. DNA was first isolated in 1869 by Friedrich Miescher. James Watson and Francis Crick figured out the structure of DNA. DNA is a double helix. The structure of DNA can be likened to a twisted ladder. The rungs of the ladder are made up of “bases” Adenine (A) is a base. Thymine (T) is a base. Cytosine (C) is a base

ABSTRACT Genetics is a trend these days especially that‚ DNA barcoding has been developed. DNA barcoding is an important tool in categorizing the taxa of different species and it tells so much about the species’ traits‚ including genetic diversity. The Pomacea canaliculata was introduced in different parts of Asia and had been an invasive species and a pest in different ecosystems ever since the introduction. In understanding this species of snails‚ samples were collected‚ DNA’s were extracted‚

The universal DNA database is important to the law enforcement agencies. The database will help the law enforcement agencies to identify suspects fast. When the universal data base is not used‚ it is very easy for a criminal to commit a crime and escape. The DNA universal database will improve the crime investigation thereby curbing the menace of criminals. When this takes effect‚ criminals might be extremely careful not to leave any trace that can help in getting their DNA for identification (Krimsky

DNA databases: crime fighting weapon or threat to privacy 1- A DNA database is a database that contains a profile of bodily fluid left by criminals at the crime scenes. It has developed by the biology laboratory of the Florida department of law enforcement. These profiles are sent to nationwide DNA bank. There are several benefits of these DNA databases. First‚ the DNA can be used as evidence in trials. It allows criminals to be identified by their own genes. Second‚ the computer analysis
