What Is Genetic Profiling?

Like fingerprints, DNA is unique, with the exception of identical twins; no two people have the same DNA. DNA profiling is a technique that can identify the person responsible of a violent

Genetic profiling is a contemporary issue relating to the individual and technology which restricts access to unbiased decisions and privacy. Genetic profiling interferes with the individuals bodily, genetic and behavioural privacy, as it can be used for the benefit of identifying bodies to using the results of a DNA test to choose whether to employ one individual over another, due to future concerns. It can easily be argued that genetic profiling is in the need of law reform as a result of legal implications and the lack of individual’s rights.

The author explains the basics of DNA by describing the simple part of it, “proteins are the molecules that do all of the work in every organism, from carrying oxygen, to building tissue, to copying DNA for the next generation” (Carroll 73). He also explained the four bases that are building blocks that are held together by strong bonds and are represented by the letters A, C, G and T. Scientist also learned that A and T always pair with each other as well as G and C, this helps them because if they know one strand of DNA they already know the second because of how the bases match up. The author states that scientists have found about 500 genes that exist in all forms of life, the author explains that these genes are “immortal”. These genes have endured millions of years of evolution and have not been mutated because they are essential for every organism to have; these genes can have important jobs such as decoding of the DNA and RNA and making

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

A DNA profile is an encrypted set of numbers w0hich reflects an individual’s DNA makeup. This encryption can also be used when identifying a person. DNA profiling is NOT however a full genome sequence. (Joseph Wambaugh, 1989)

Indeed DNA profiling has rapidly transform the field of forensics. DNA profiling is the scientific analysis of evidence for crime scene investigation and other legal proceedings. DNA profiling is mostly used by forensic scientists and crime lab technicians. To identify criminals and victims using trace evidence like hair or skin samples. To produce a DNA profile, scientists compare sequences in the genome that vary from person to person. The typical steps in DNA profiling are DNA samples are isolated from the crime scene, suspect, victims, or other evidence. The next selected sequences from each DNA sample are amplified (copied many times) to produce a large sample of DNA fragments. Finally the amplified DNA regions are compared using a gel. All together, these steps provide data about which samples are from the same individual and which sample is unique.

The DNA contains four types base: A (adenine) and T (thymine), G (guanine) and C (cytosine). These four letters make up the genetic alphabet and they spell out the commands for every single cell and organ of the body and also determine all the characteristics of the person.

Hook: Have you ever thought about your personal DNA and why it is important to you? Besides showing factors of how you grow, develop, and function, your DNA has more to it. What is DNA profiling? DNA profiling is when someone uses DNA to identify someone, make sure someone is not being wrongly accused, or to claim criminals. But there are pros and cons to DNA profiling. This is because some people are for it and others are against it.

Do you ever wonder why your hair is the color that it is? Or where you got your height? Well this is all dependent on your genes. The genes that you have were passed onto you from your parents. Geneticists the people who study our genes and heredity. They do extensive research and study how genes work and how they are built. Geneticist don’t just learn about humans, depending on what part of the field they are working in they may also learn about plants and animals. All of the data that they collect from research they use to find new medicines and cures for all different kinds of diseases. Like I said they also work with plants and animals. They work with plants by trying to change the genetic makeup of crops to help improve the

“Deoxyribonucleic Acid, also known as (DNA), was first introduced in the 1800 by Alphonse Bertillon, a French Anthropologist. DNA, which defines the hereditary make-up found in humans and other living organisms, can be obtained from the blood, saliva, sweat, hair, and urine. DNA profiling was mainly used as a method of determining paternity.” (Cormier, 2005). In 1986, DNA was first introduced into the courts when investigator’s in England asked molecular biologist, Alec Jeffreys, to use DNA to verify the innocence of a 17 year-old boy. He had been identified as a perpetrator in two rape-murder cases in the English Midlands. The tests proved that the teenager was in fact innocent and was not the perpetrator of the crimes. Because of DNA testing the perpetrator was eventually

Genes is the physical and functional unit of heredity which are made up of DNA. It carries the information of that determines traits that are passed on by the parents. There are two copies of genes which comes from each parents which is to be exact twenty chromosome from each parent to make up forty six chromosome in a baby. As by the

DNA and ribonucleic acid are nucleic acids; alongside proteins, lipids and complex carbohydrates, they are one of the four major types of macromolecules that are essential for all known forms of life. DNA is shaped like a double helix. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

It is incredible to think that a single piece of evidence can be used to convict or acquit a suspect, but such is the case with DNA profiling. Throughout the past few decades, DNA profiling has evolved immensely from a genetic fingerprint discovered by Sir Alec Jeffreys in 1984 into an aspect of everyday forensics affecting millions of cases and trials today. Since a suspect’s conviction or acquittal rests on the proper collection of DNA evidence, regulations have been put into place, as a result of the ‘DNA wars’, to ensure the evidence is admissible. DNA profiling has been made famous through trials such as OJ Simpson versus Nicole Brown. Genetic fingerprinting has also begun to branch from the forensic field into discovering a person’s ancestry

DNA is a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairs which look like the

Chromosome- Chromosomes are the microscopic structure within cells that carries the molecule deoxyribonucleic acid. DNA is the hereditary material that influences the development and characteristics of each organism. In bacteria and bacteria-like organisms called archaebacteria, chromosomes are simple circles of DNA that float around in the cell. In more complex cells, or Eukaryotes, chromosomes are stored within a well developed and defined nucleus. In eukaryotic cells, chromosomes are highly complex structures in which the shape of the DNA molecules is linear, rather than circular. Chromosomes consist chiefly of proteins and DNA. Tiny chemical subunits called nucleotide bases form the structure of DNA. A sequence of these bases that are along a DNA strand will create a code for the production of a special protein also known as a gene. Genes occupy precise locations on the chromosome. Each cell contains enough DNA to form a thread extending about 2 m (about 7 ft). Proteins called histones play a key role in packaging DNA within chromosomes. Sections of
