What is DNA Where is it found Essay - 660 Words

What is DNA? Where is it found? What makes it so special? How does it work? DNA (Deoxyribonucleic Acid), is defined as a heredity material in humans or all over other organisms in this world. In a person’s body, nearly every cell has a same DNA. Mostly DNA can be found in cell nucleus and few are found in Mitochondria. (Christine A.Evers, 2012). †¢ COMPONENTS OF DNA: The DNA information is stored as a code and they are made up of four chemical bases: †¢ Adenine (A) †¢ Guanine (G) †¢ Cytosine(C) †¢ Thymine (T) According to my opinion, DNA just affects about everything in a human body, DNA holds all the information needed to proteins and all other traits also that directly affect an organism’s†¦show more content†¦What actually is different in DNA that makes a person different from the other oneIts basically the different pairing of those 4 base codes that we discussed initially; Adenine, Guanine, Cytosine, Thymine. Everyone in this world have these four base codes in their DNA but the different thing is the different pairings of these base codes. The difference in order or sequence in each person makes him different from the other one. (â€Å"How DNA works†, 2014). One of the important significance of DNA is in genetics and medical research. We are now able to identify and diagnose many diseases at their early stages. Regarding genetics,Individuals susceptibility to a disease can also be diagnosed by the help of DNA. On the other hand,This help has given us a great opportunity to make drugs for the diseases which were previously considered as fatal and non curable.Medical research can answer about those diseases which were questionable before. â€Å"(The importance of DNA†, 2014). We have already discussed about the role and importance of the DNA before and its role has the same im[portance in every field but its contribution in medical world has helped a lot of families and children.We all know about the paternity cases.It used to be aShow MoreRelatedDetermining Who Boy # 1 s Biological Parents Are With The Use Of Dna Fingerprinting1136 Words   |  5 PagesB and Tiarne N Date: 09/09/14 Aim: The aim of this experiment was to determine who boy #1’s biological parents are, with the use of DNA fingerprinting. Hypothesis: If DNA samples are collected from different mother and fathers, then it can be determined which DNA samples have common genes fragments. Background: Deoxyribonucleic acid, or in its’ simple form DNA, contains the code for all characteristics of an organism which is completed by a double helix structure. The structure is made up ofRead MoreThe Effects Of Uvb Waves On Dna Bases1157 Words   |  5 PagesBianchi, J. et al. 2013). But what exactly is ultra violet radiation? The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB) There’s also a third type of ray, UVC, these are the shortest and strongest, but they are absorbed by the ozone layer and don’t typically reach the Earth ( Bianchi, J. et al. 2013). However, in many experiments UVC is used. What We Already Know on Effects of UVB Waves on DNA Bases. UVB radiation isRead MoreEssay On Circular Dna Throws Biologists For A Loop946 Words   |  4 PagesCircular DNA Throws Biologists For a Loop In her article Circular DNA throws biologists for a loop Elizabeth Pennisi of Cold Spring Harbor, New York. Examines several developments in the case of mysterious loops known as extrachromosomal circular DNA (eccDNA). Scientists have known about these circular DNA for decades they were first found in the nuclei of plant cells and later in brain cancer cells. At the time scientists speculated that these circular DNA may give brain tumors a genetic boostRead MoreThe Importance of Dna Evidence1575 Words   |  7 PagesThe Importance of DNA Evidence 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, mucusRead MoreThe Molecular Structure Of Dna1371 Words   |  6 Pagesâ€Å"Deoxyribonucleic acid, or DNA is the molecule that transports most genetic instructions utilized in the growth, function and biological process of all living organisms and many viruses.† (Merriam-Webster Dictionary) It was first discovered at the University of Tà ¼bingen by Friedrich Miescher in 1869. Miescher discovered DNA through a microscopic substrate in a sample of pus on unwanted surgical gauze. (Dahm) Nature is a scientific journal in Britain, where studies and academic research in scientificRead MoreDNA Conviction And The Truth Behind It In the world of forensic science, exoneration holds a very800 Words   |  4 PagesDNA Conviction And The Truth Behind It In the world of forensic science, exoneration holds a very crucial role. In cases where a person has been convicted of a crime and needs to be proven innocent, exoneration plays a key part. It is what helps the court to decide in a just manner whether the crime was committed by that person or not. Exoneration is based on DNA evidence and therefore, is the most authentic. The main purpose of exoneration is to help the legal system by allowing innocent peopleRead MoreDna Research Paper809 Words   |  4 PagesThe discovery of DNA began in 1928 when the British bacteriologist Frederick Griffith was performing an experiment with mice based on pneumococcus, a bacterium that causes pneumonia in humans. This bacterium has a capsule made of polysaccharides that has a shiny and smooth appearance, called s-strain. There are mutants of s-strain that do not produce this capsule and form a rough-looking colony called r-strain. Griffith discovered that this mutant did not kill the mice, but if p neumococcus R wasRead MoreShould Federal Agents Be Allowed For Collect Dna From Anyone Arrested?1228 Words   |  5 Pagesto collect DNA from anyone arrested? This is a controversial issue. In my opinion, DNA is a very powerful and useful tool because many sex crimes go unsolved because of lack of evidence, but if federal agents can look in a database where DNA samples are stored and compare it to anyone who was arrested especially those who committed sex crimes more crimes would be solved. Many say DNA testing violates suspects rights under the Fourth Amendment of the Constitution of the United States. DNA testing hasRead MoreDna Evidence Of A Dna Unit Within A Crime Lab1551 Words   |  7 PagesToday 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 b eing 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. Let’s start by defining what in fact is DNA analysis. According toRead MoreHow Deinococcus Radiodurans Is A Member Of The Bacteria Kingdom894 Words   |  4 Pagesmore specifically, the Deinococus genus. It is spherical in shape, and approximately 1.5 to 3.5  µm in diameter. It is usually found in tetrad formation: where four individual cells stick together. D. radiodurans isn t known the cause any diseases, nor does it form endospores, and it stains gram positive. It is non-motile, and an obligate aerobic chemoorganoheterotroph. What makes D. radiodurans so unique, is its ability to withstand ionizing radiation, UV light, desiccation, and even oxidizing and
