The Doll

I was five when I got the doll, not giving a care in the world to my surroundings. The doll was weird looking, almost terrifying to look at, but the doll looked to me interestingly enough to keep it and play with. She had a red top hot with a blue ribbon wrapped around it with midnight blue hair by the looks of it with light blue for her bangs, her hair in two ponytails in the upper back part of her head. Her left eye was stitched up and the right though liked like the kind that can be used for any emotion to speak of with the color of ice blue. She had a dress that covered her neck, her upper body and leggings for pants, on the feeling of the material. Her shoulders, forearm, and her nails painted black. Her shoes, just plain black with flat boots, able to take off and put back on. Doll also had pink spider earrings that was very detailed to the very inch.

With over three million base pairs in the human gene, forensic scientists are able to distinguish a person’s genetic makeup.

(PCR), which isolates small fragments of DNA that have a high degree of variability from

2. The millions of copies that are created from a meager amount of DNA assist the laboratory in generating a DNA profile that will be compared against the DNA profile of the suspect.

The Australian Institute of Criminology has produced documentations explaining “the technique of ‘DNA identification’ compares the DNA of two bodily samples to ascertain whether or not they came from the same human being. Identity of DNA in the cells across both samples implies that the samples are derived from the same person (or identical twins); non-identity implies different human sources.”

exception of identical twins, DNA fingerprinting is a reliable method used to determine the parents of a given baby. DNA fingerprints can be derived from restriction

code” that is unique to every person. Junk DNA in investigations can usually be found in saliva,

Each person's DNA is unique . DNA biometrics technology is highly unique .The chance of two individuals having the exact same DNA is extremely impossible .Moreover ,DNA biometric technology impossible to fake because each person's DNA contains some unique trait from parents. DNA biometrics technology used in security systems but this technology is still new and it is hardly applied in public.[15]

Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem

Every day DNA technology becomes more advanced and innovative, for example can match the smallest amounts of biological evidence to a criminal offender. Future DNA techniques will be applied to existing systems and testing methods that will become more automated and will be more effective and less time consuming. Instead of waiting months of DNA results the future will provide instantaneous means for DNA profile development.

DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.

Law Enforcement keep notes on arrests that have founded people innocent of crimes, and retention of an innocent person's DNA can be charge or otherwise, seen as a invasion of that person’s privacy and civil liberties. Dr. Alec Jeffrey, a former professor at the University of Leicester laboratory, consulted with his lawyers to develop the new type of technique called DNA profiling. His technique would prove that DNA fingerprinting (profiling) can individualize evidence compared to the blood typing. DNA profiling compares 13 standard STRs to form a profile. The analysis used by the scientists, uses PCR and STRs to profile an individual. It is highly unlike that two individuals’ identical numbers of repeats for all 13 STRs, will match, which DNA fails is hardly never due to a successful match of 385 million to 1. This makes DNA profiling the most accurate tool in Forensics.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

DNA is deoxyribonucleic acid, which is found in almost all living things. DNA serves as a code for the creation and maintenance of new cells within an organism. Within humans, it is found in almost every cell. Although most of our DNA is found within the nucleus of our cells as nuclear DNA, a very small amount of our DNA is also found within the mitochondria as mitochondrial DNA. Because mitochondrial DNA is generally not used for solving crimes, for the purpose of this paper it will be disregarded.

Finally, all the nucleotides are joined to form a complete polynucleotide chain using DNA polymerase. The two new DNA molecules form double helices.
