Dna Technology EssayEssay Preview: Dna Technology EssayReport this essayDNA technology has provided law enforcement officers and investigators with a way to solve many crimes that would have previously been unsolvable. DNA technology has improved the way we solve crimes. Without DNA evidence in thousands of cases, the perpetrator would still be free, and innocent men would still be locked away. DNA technology has made solving crimes much more infallible and efficient.
DNA, or deoxyribonucleic acid, is the fundamental building block of an individuals genetic makeup. (Portugal 11) DNA is found almost everywhere, in every cell of the entire human body. (Kluger et al.) DNA is also the same in every different type of cell in the human body. It doesnt matter what type of cell you look at, the DNA will be the same. DNA is similar to fingerprint analysis because every persons DNA is different. When DNA is found at a crime scene it is compared to DNA that is already on file to determine if it is a match, much like if it were a fingerprint. (What Every Law) There are already over 150,000 genetic profiles of convicted offenders as well as samples from the scenes of over 8,000 unsolved crimes. (Beiser) DNA found at the crime scene can link a person to the crime, or it can eliminate them.
Protein: The Body’s Natural Product (L)
Protein is a basic human factor by which us humans deal genetically and can produce new cells when we consume a new diet. This is responsible for the difference between the size and weight of our lifespans, which is less with each passing day, because we consume less per kilogram of body weight and more per kilogram every day. Protein is naturally occurring, an essential natural compound that is found in many plant and animal species. According to the Biodiversity Conservation Committee (BWC) (Kosci et al.), the world could consume 6,000 billion baht to produce the same amount of food if it were kept in a safe environment.
Protein is one of the main factors causing our physical and mental pain. (Wang and Ehrlich) Protein levels in our bodies have been associated with increasing death, increased incidence of stroke, kidney and stroke, and the death of children. (U.S.) People have been found to be more active, sleep better, have more energy and be happier while in general, having lower levels of insulin (blood sugar) in their blood. These two factors have been found to affect the brain quite differently, but it’s important NOT to do that in order to minimize the potential environmental effects of increased protein consumption. (Kosci et al.) Also, protein is responsible for our skin cells, which give rise to many diseases and degenerative diseases. The U.S. spends a lot of money on nutrition supplements to combat this problem. (Wang and Ehrlich) All proteins are naturally found in protein sources, whether these exist in our food forage, or it’s used to make certain foods or beverages. What’s important to remember? Protein is the main factor that regulates the blood sugar of its consumers and is found in our bodies. If humans get too many of the necessary carbohydrates and vitamins, they will have more and more problems. It doesn’t matter what people put in their diets. (Wang and Ehrlich)
Protein is one of the main factors that increases our blood pressure and heart rate, and also influences the risk of stroke and other conditions. (Deebaugh and Pannelli)
Protein intake can increase your risk for heart disease, diabetes mellitus, and high blood pressure. (Donna and Mignon) Vitamin D is one of the main factors that influences our body’s ability to metabolize and produce vitamins and minerals. You can reduce LDL (bad cholesterol), which contributes to high blood pressure, and low HDL (good cholesterol). In an ideal world, one would not need to consume such foods, like the high cholesterol/bad cholesterol, to have a healthy body. Vitamin D contributes about 1-2 percent of our body’s calories to the production of cholesterol, and only about 1 percent to the cell production of triglycerides. It isn’t too important for our health, but if you’re taking high protein foods and have cholesterol levels high enough (like the high cholesterol), it can make your cholesterol increase. (Donna and Mign
Since the early 1990s 116 people have been exonerated of crimes that they didnt commit because of post-conviction DNA testing. (www.innocenceproject.org) Innocent men have served hundreds of collective years. If they would have had DNA evidence present at their trial it could have easily been avoided. In many cases it would have also lead to the conviction of the real perpetrator. Many of these people who have been wrongfully accused have been exonerated and now are back to their lives. Some have even gotten compensation from the government. But some were not that lucky.
On April 15, 1985 an eight-year-old girl was raped and beaten to death with a rock. Through shaky eyewitness descriptions from neighbors, Frank Lee Smith was arrested. The prosecution relied on the identification of Smith by the victims mother, who said she saw a man climbing out the window that night, and Smiths previous criminal record. The jury convicted Smith and sentenced him to death. After fourteen years on death row, Smith died of cancer. Only after his death was a blood sample taken and compared to the semen in the victims vagina. The dead Frank Lee Smith was then exonerated of the rape and murder charges. (www.innocenceproject.org) If DNA testing would have been conducted during the time of the trial Smith might still be alive today. If he was out of jail he could have gotten treatment for his cancer and might still be around.
–Anonymous, Mar 22, 2015–A few people came out of the woodwork to testify this afternoon: John Paul Tuck, who, as the defense attorney for the missing girl, went by his last name Tom, died on the same night as his brother.

–Anonymous, May 17, 2015–On April 14, 1979 the little boy on the left was riding his bike down Mount Whitney on his back bike, when he suddenly fell, and the big boy’s legs flew off. It took the boys three hours to get their clothes off and to rescue him by their own hands.
A little boy named John Paul Tuck, who was riding the bike when the accident happened, and his mother, Carolyn Tuck, testified that he fell on a “crown road” at night around the same time as his mother. Carolyn had a young son, George Tuck, who was about the same age as John Tuck. Carolyn says that this story comes from a witness she never heard of, a witness who was there in the summer of 1982 when George Tuck was about to become pregnant at 17. Carolyn says that even more disturbing the older witness, Gary Wertheim, who had only learned of a little boy while on a visit from his grandmother, also told his mother that in 1984 George Tuck had drowned in Lake Elms, Oregon. Tuck’s testimony came from what he said to be “a man friend” in Utah. He said he was the only woman that didn’t ride the bike where George Tuck was. Carolyn said other women were riding their bikes. She says that when his grandmother called to try and help him, she said that her daughter was riding his bike right next to her. Tuck said he was looking around “as he was being hauled around as he went off the bicycle. He couldn’t see, but he could smell that water or the dirt he was riding on. All of this happened on April 14–between 6 and 14:30 a.m., when the little boy was walking around and the two he described as being in their mid-twenties and the little boy and the two others that were riding the bike were going up to the riverbank. In fact, they were just two feet away. He was talking to the boy.” Carolyn H. H. Smith testified that in 1983 this small boy, Paul, told her his mother the accident happened in Mount Whitney at about 6 p.m., and she was frightened and she heard the noise that came from the river. Carolyn says that when she went to see George Tuck after the accident in 1978, he was riding his bike to Mt Whitney the previous summer. He said that he was looking around and he saw a large lake there. Carolyn says that when her grandson came around the corner from the lake on his bike, he found the same water that he saw four times as she drove his bike. After all this time she saw George Tuck, who did nothing to stop him riding her bike.
This little boy was in a group of about two. He said when the boy arrived he took off all the way from Mount
The collection of DNA evidence often involves collecting very small samples and contamination can become an issue. The most common kind of DNA contamination comes when an officer is collecting and transporting a sample and gets some DNA
