DNA Sequencing In Science And Technology

Improved Essays
DNA sequencing and information is useful in many fields of science and technology. DNA ideally can be used to identify specific organisms because most organisms don’t possess the same DNA.The use of DNA to try to identify specific organisms is called DNA fingerprinting. DNA fingerprinting involves creating a DNA fingerprint using gel electrophoresis, which is the process by which DNA is broken down into fragments and then sorted by positive electrodes (after negative electrodes repel them from the other side. And as this happens the DNA strands for lines of different lengths resulting in an identifiable pattern. There are wide array of uses for DNA fingerprinting. For example DNA fingerprinting can be used to distinguish the relationship (or …show more content…
“All the hereditary information of an organism makes up it genome.” The genome of an organism is partially determined by the sequence of bases. The Human Genome project was founded 1990 and had a major goal of identifying and mapping all of the genes in human DNA, numbering about 20,000-25,000 genes and about 3 billion chemical base pairs. This project was completed in 2003 and contributed to the development of our modern knowledge of human DNA. This information is available to scientists worldwide and has prompted the researching of the genomes of several different species. This information can help determine the health of human by comparing abnormal DNA sequences with that of a typical DNA sequence. The Human Genome project also leads to developments in gene therapy; by determining exactly what mutation caused a disease scientists can, theoretically, replace those genes using gene therapy and help solve the issue. Even with the help of the Human Genome Project there is still many factors that limit gene …show more content…
cells can be used to produce insulin whenever the reproduce with recombinant DNA. Cloning is the production of an identical copy of an organism, or DNA artificially. This can be used in a variety of ways from recreating cells to recreating endangered species. Cells that are unspecialized are called stem cells. Stem cells are believed to possess the ability to replace cells the cannot regenerate which can lead for treatment of heart, nerve, and brain disease that involve not enough cells performing properly. There is opposition to the idea of genetic engineering as many people think that, if done in humans, people will be able to choose traits of their baby right away. Stem cells are also controversial as one of the main sources of them is embryonic tissue which some see as a potential baby. The most prominent argument against genetic engineering is the idea of genetically engineered crops and food. Many people are opposed to this idea because scientists are unsure of the effects of genetically engineered crops. Another risk of genetically engineered crops that is less obvious is a reduction in the genetic variation of crops (meaning that if there is a disease that kills this particular crop they will all die because there is no genetic

    If you had told someone in the early 1800’s that every cell in your body contains something called DNA made of molecules called nucleotides (DNA) that determine every characteristic about you, from your height and eye color to whether or not you’ll get a certain disease or condition, they would think you were crazy. Today, most students learn about DNA in middle school biology. DNA was first discovered by a German biochemist named Frederich Miescher in 1869, but its importance was not realized until 1953 (DNA). Genetic testing, “a type of medical test that identifies changes in chromosomes, genes, or proteins” (What is Genetic Testing?), however, was first done in the 1910s with ABO blood typing (O’Neil). Today, testing is used for determining paternity, determining a person’s chance of developing or passing on a genetic disorder, and to confirm or rule out a suspected genetic condition (What is genetic testing?).…

    Life Without Sequence On October 5th, 1984, the body of 15-year-old Kristina Hickey was found raped and stabbed behind a mall in Park Forest, Illinois. She had been missing for two days, having last been seen walking on her way home from choir practice. On January 15, 1987, Christopher Abernathy, who was seventeen at the time the murder was committed, was convicted of Hickey’s murder and sentenced to ‘Life’ in prison without the possibility of parole. Abernathy’s sole accuser was a high-school friend who claimed Abernathy had confessed to him, and a suspiciously obtained confession, by Abernathy, to the police.…

    Fetal Stem Cell Research Pros and Cons Stem cells have the capacity to create other cells in the body, such as brain, muscle, tissue and blood cells. This is why it is considered a revolutionary option to repair or replace damaged cells or tissues, as in the case of cancer. Stem cells are present in all of our bodies and for the entirety of our existence. But its potency is highest in a fetus than in an adult body, resulting in fetal stem cell research. The negative and positive effects it would have on a fetus led to a heated debate about embryonic stem cell research, as it is also called.…

    For about three decades many scientists did not believe DNA contained genetic material because it was not seen as complex due to the fact not much was known about it yet, so many presumed proteins were the genetic material of life. It was not until scholars such as Frederick Griffith, Meselson-Stahl, James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin, Avery, McCarty, Erwin Chargaff and many more conducted experiments that would expose astonishing discovering that will lead to the understanding of DNA also known as the Race for DNA. It began with Frederick Griffith’s Experiment “Transforming Factor”, conducted in 1928 testing bacteria for pneumonia and injecting them into mice. He noticed something was being transferred from the smooth strain to the rough strain when he mixed them together; he did not know what…
