Introduction

DNA analysis is the process in which evaluates the genetic material so that it can be used to identify individuals for use in a forensic/criminal investigation. DNA, or deoxyribonucleic acid, is the hereditary material that is found in almost all organisms. It is found in the nucleus of the cell and also small amounts can be found in the mitochondria and nearly each cell in a human’s body has the same DNA. But what is DNA made up of? Well it is made up of a code of four chemical bases which include adenine (A), thymine (T), guanine (G) and cytosine (C). Only adenine and thymine can pair up with one another and it’s the same with cytosine and guanine. Each of these bases are also attached to a glucose molecule (C6H12O6) and a phosphate molecule (P). …show more content…
Tests to determine the likelihood of paternity are considered to be 99.99& conclusive and can be used in establishing child support orders. Not only is DNA testing used to determine paternity but it is also used to determine other family members which include twins separated at birth. Sometimes hospitals confuse children and give the parents the wrong baby, however, maternity testing can conclusively identify which child belongs to the mother.

DNA testing can be used to determine whether a person is at-risk for developing a disease. If it is found that a person is at-risk for a disease they can take the necessary action to reducing the risk. DNA testing can determine whether parents are carrying genes that can affect their child.

A major issue/concern regarding DNA testing is data confusion. When testing is used inappropriately can create a system of wrongful convictions. Errors such as contamination of DNA are used to make a certain outcome in court. But the contamination of DNA can be monitored quite easily by controlling access by unauthorized personnel and separating of work areas for evidence examination and DNA

list of ‘things most hated’. Certification of a testing site, deemed unrequited by the American Society of Crime Laboratory Directors, takes away the ability of having testing standards within the industry, fully trusting the information found was all the evidence present at a crime scene, and the collected data authenticity.

Essay on Bacterial Transformation Report

Transformation Lab Report I. Pre-lab Bacterial transformation occurs when an organism receives DNA from a different species and expresses the implemented gene, thus becoming a transgenic organism. The practice proceeds as follows: first cut the plasmid from one organism and DNA from another, using the same restriction enzyme on a palindromic sequence. The recombinant plasmids then enter the host bacteria and asexually reproduce infinitely. We can identify that the bacteria has the new DNA by testing to see…

Animal Testing Research Papers

Each year, PETA estimates over 100 million animals are killed in the U.S. alone in animal testing, including mice, rats, frogs, dogs, cats, rabbits, hamsters, guinea pigs, monkeys, fish, and birds (PETA, “Experiments on Animals”). These animals are subjected to invasive and damaging tests, ranging from slight skin irritation to lethal poisoning and seizures. In 2003, animal protection groups released a report of CPCSEA inspections done in 467 laboratories in India. The findings revealed experiments…
