The Discovery of DNA Essay

The basis of genetics were established by Gregor Mendel, an Augustinian monk in the mid to late 1800’s. Through the observations from cross-pollinating pea plants, Mendel was able to discover the basic laws of inheritance. Mendel’s experiment was to cross pollinate pea plants and observe how traits were passed on. He started his experiment with two true breeding pods,

The prospect of a genetic database in Australia has been raised recently. The federal police are pushing for a national database to help solve crime and are asking for legislation to be allowed to collect DNA samples from people accused, or suspected of committing an offence (the Australian, 06.12.1997 see appendix one)

Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

II. As Louis Pasteur put it “The infinitely small in nature is infinitely great.” This quote gives a perfectly accurate description on how something as microscopic as DNA could have such an extensive role in our lives. Just a small piece of DNA can help investigators solve cases and assure that the correct person is being punished.

The discovery of deoxyribonucleic acid, more commonly known as DNA, has been the foundation for much scientific work. This fundamental discovery was credited to James Watson and Francis Crick. Many people believe that another person, Rosalind Franklin, also played a large role in the research. How much did she contribute to the discovery? Why is her name left unrecognized? This paper will discuss her part in the search and whether her name should appear next to Watson's and Crick's as the co-discoverer of DNA.

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.

This book has been molded to be a breakdown of how various fields in science have progressed over centuries as mankind has advanced. The book starts off introducing the idea that the telling of natural history has changed numerous times as humans have evolved. We also learn to agree that our knowledge has been shaped by the tools available and the perceptions of its users. In the earliest stages of life, Muehlbauer states “…observers of the natural world had only their senses to work with, and were limited to visual, auditory, tactile, and olfactory descriptions perceived by the unaided

DNA is a term that has been used in science as well as in many parts of daily

Currently, the DNA examined and recorded for forensic purposes does no reveal the most personal of these details but the technology for doing this exists or is likely to exist in the future. The ability to use DNA to make family connection is currently the main issue raised by the use of DNA technology in law enforcement, which is bound to result in futuristic invasion of privacy or possible harassment of those who happen to be family members of possible

Former attorney General Janet Reno described our system of justice as a search for the truth.(1) Increasingly, the forensic use of DNA technology is an important ally in that search. DNA fingerprinting, better known in the scientific realm as DNA profiling, has given police and the courts a means of identifying the perpetrators of rapes and murders with a very high degree of confidence. However, nine years after its introduction, forensic DNA typing is still used only selectively. This is due to a variety of factors, including the unavailability of forensic typing to local prosecutors, the time required to perform the typing, and the costs of the tests if private laboratories are utilized. Formerly

Improper forensics, bad lawyering, snitches, unqualified “experts,” eye witness misidentification, false confessions, and mishandled evidence are all just a few reasons for wrongful convictions in the justice system. However, the authors of Actual Innocence: When Justice Goes Wrong and How to Make it Right, discuss how DNA is a main factor into “actually innocent” people. Throughout this book we learn stories about those who were wrongfully convicted and later proven guilty for reasons such as DNA testing. While this proves to us that not everyone convicted is guilty, it points out many other errors in the criminal justice system as well.

DNA creates human beings. When we are created in the womb, we are just two strands of our parents DNA mixing together. DNA encodes the genetic information that is necessary for the growth, development, and reproduction of an organism.

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.

material of some viruses. RNA molecules are like DNA. They have a long chain of
