Dna Informational Summary

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.

DNA collection is a good thing not only can it help catch the person responsible for an illegal crime, but it can also clear up a suspect’s name. In the case of Maryland v. King on April 2009 Alonzo Jay King was charged for first and second degree assault for scarring a crowd of people with a shotgun, he was arrested and as a part of their booking procedure, they swabbed Alonzo Jay King for his DNA. Kings DNA sample later resulted to be a match of a DNA sample in the system “CODIS” of a rape victim by the name of Vonette W.’s Salisbury. Vonnette was raped on September 2003 but had not gotten justice for the crime against her since the only evidence was the DNA sample of the semen that was swabbed. No matches were found in the data base until Alonzo Jay King was arrested. By collecting DNA, it can help lead to an arrest of a suspect and to be able to close cases.

Today in the crime world, DNA evidence is strongly accepted in solving crime cases. This is all based in part by allowing a crime laboratory to have a designated unit whose main goal is to analyze DNA evidence to aid investigators with positive outcomes in crime case solving. With that being said we are going to discuss the functions of a DNA unit within a crime lab as well as address the vital role these units play in solving crime.

DNA is spread by an organism to an offspring during reproduction and inherit traits half from the male parent and the other half from the female. DNA can be very useful in crime scenes since DNA can be found through fingerprints, fingernails, mucus and blood. Although DNA is not always the most accurate since some convicted people are often innocent because fingerprints can be contaminated easily. On the other hand, hair protein sample test has been proved incorrectly by only 1.98 percent and scientists only need one single strand of hair to identify one person out of a

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.

Basically, our DNA (deoxyribonucleic acid) is our genes, and every person, except for twins, are born with a different DNA profile and that is in a giant database, containing every DNA profile of every person in the world. DNA testing started in 1985 by scientist Alec Jeffreys and was first used to solve a crime a year later. Before 1985 DNA evidence could not be used in court because it wasn’t invented yet, this increased the number of wrongful convictions which would have been prevented using DNA analysis. However, DNA analysis can still be used to solve crimes that occurred prior to the invention of DNA analysis, with a sufficient amount of DNA to be analyzed of course, which is a very small amount. Only a small amount of DNA is needed to find out who it belongs to, it can be found in blood, saliva, finger residue, hair, skin, semen and more.

DNA testing is a critical and accurate tool in linking accused and even convicted criminals for crimes, and should be widely used to assess guilt or innocence before jail sentences are imposed. It was started up by scientists Francis C. Crick and James D, Watson in 1953 as they had described the uses, structures and purpose of the DNA “deoxyribonucleic acid” genetic fingerprint that contains organism information about an individual (testing

Qualities of the Hero: Comparing Gilgamesh and Odysseus A hero refers to someone who has done something outstanding during their generation. It’s someone who stands out for is extra-ordinary deeds in the society. A hero shapes the life of the future generation. They form the basis of what the future generation can look up to and learn from them.

DNA analysis is a forensic tool that allows a suspect to be linked to a crime scene. Using the DNA analysis method, requires law enforcement officers to obtain DNA from the suspect and compare the suspects DNA,

DNA forensics can also narrow down suspect pools, exonerate innocent suspects, and link crimes together if the same DNA is found at both scenes. However, without existing suspects, a DNA profile cannot direct an investigation because current knowledge of genotype-phenotype relation is too vague for DNA phenotyping. For example, a profile from a first time offender that has no match in any database may give the information that the criminal is a left handed male of medium stature with red hair and freckles. It would be impossible to interview every man who fits that description. However, with available suspects, DNA forensics has many advantages over other forms of evidence. One is the longevity of DNA. Although it will deteriorate if exposed to sunlight, it can remain intact for centuries under proper conditions (Sachs, 2004). Because DNA is so durable, investigators can reopen old cases to reexamine evidence.

Due to the uniqueness of DNA it has become a powerful tool in criminal investigations

Human DNA is very similar to one another, but only about 0.1% is different from the next person. That 0.1% can tell a person’s eye color, hair color, and other physical features. DNA analyst are able to take a drop of blood, the size of a dime, and duplicate the number DNA found in that drop. With the ability to duplicate DNA, analysts can have a back-up, in the event a human error were to occur. Analyst can tell you exactly where your ancestors came from and the percentage that is still inside your DNA. DNA is a very powerful tool that can identify a murder if the individual left any blood, saliva, skin tissue, hair or semen. The education needed to be able make use of the DNA consists of a great deal of science classes.

Deoxyribonucleic acid (DNA) has been used to analyze and prove innocence or guilt of suspects of crimes with great accuracy. DNA is part of everyday life. It is the heredity material in humans and almost all other organisms. While being part of an investigation. DNA has helped to solve crimes. There is a couple ways that DNA left behind can be tested to solve a crime. Either if the suspect has been caught and or had his or her DNA tested, or if he or she has left behind any biological evidence. Which then needs to be tested to see if it matches the DNA found in the crime scene to his or hers DNA. The result to this comparison may help establish if the suspect committed the crime.

In the novella, Metamorphosis, every character has a major role and impact on how the story turns out. The novel is largely centered around Gregor Samsa, who turns into a verminous bug overnight. After losing his job, the family is forced to make ends meet in order to pay off their debt. Following the transformation, people begin to treat him differently, including his own family. Even though his family begins to adjust to daily life with a “vermin”, they still don’t see him the same as before. His father and mother refuse to see him, to the point where his father becomes furious with Gregor when his mother sees him for the first time and faints. Grete is the only one who doesn’t refuse to see Samsa and takes him as her responsibility. Besides

The first question that I was presented was, “What type of career is it preparing you for?” That is really a hard question to answer properly. I have had many ideas of different careers that I have wanted to be in. Each career option I have thought about don’t really coincide with each other that much. When I was younger I thought of being a Paleontologist. Thanks to my reading of Jurassic Park and having the movie. I was only seven at the time but that is what I want to do. Later on I wanted to be a storm chaser. I still think that is a cool but crazy career option. However, I really didn’t want to deal with all the weather science and meteorological studies. Then once I was in junior high I started to learn more about computers and programming. I was not the top of my class but I was thinking way further ahead than my peers. In high school I was introduced to more advanced computer ideas but not too much in the programming side of things.
