There are many interesting facts about DNA and the Gene. DNA can do an amazing number of things, such as replication and mutation. DNA and the gene are the reason that we look the way we do. DNA is structured in a certain fashion and functions in a certain fashion. Genes are used for forensics and genetic engineering. DNA can also be mutated, causing deformities. Gregor Mendel is known as the founder of genetics. RNA is also heavily used in replication. There are several types of RNA. The process in which RNA is copied is called RNA transcription.
DNA has a specific structure composed of nucleotides. Nucleotides are composed of a sugar, a phosphate group, and a base. A DNA molecule is made up of two polynucleotide chains, forming a double helix. Adenine pairs up with thymine to make one nucleotide chain and guanine is always paired with cytosine to make another nucleotide chain. In viruses, DNA molecules can have anywhere from 5,000 to over 200,000 nucleotides. A human cell contains more than 3 billion pairs of linked nucleotides. The DNA molecule is very tightly packaged. The packed form of DNA is a chromosome. DNA unwinds so that it can be copied.
An organism’s complete set of nuclear DNA is its genomes. The function of DNA is hereditary instructions determining the sequence of amino acids and making up …show more content…

Mutations are permanent changes of the nucleotide sequence of the genome of an organism, virus, or DNA with extra chromosomes. Mutations can be caused by radiation, certain chemicals, sunlight, temperature, using drugs or alcohol while pregnant, an extra chromosome in DNA, a missing chromosome in DNA, and many other things. The resulting change in nucleotides is called genetic mutation. Some mutations are harmful, and some even fatal. Some mutations have developed entirely new species. Mutations can cause autism, hemophilia, albinism, Huntington’s disease, cystic fibrosis, sickle cell anemia and many other

  • The Pros And Cons Of DNA Analysis

    1216 Words  | 3 Pages

    DNA is the genetic material found in cells of all living organisms. Human beings contain approximately one trillion cells (Aronson 9). DNA is a long strand in the shape of a double helix made up of small building blocks (Riley). The repeat segments are cut out of the DNA strand by a restrictive enzyme that acts like scissors and the resulting fragments are sorted out by electrophoresis (Saferstein 391).

  • Case of Kirk Noble Bloodsworth

    1714 Words  | 4 Pages

    DNA is the blueprint of life. It stores our genetic information which is what is in charge of how our physical appearance will look like. 99.9% of human DNA is the same in every person yet the remaining .1% is what distinguishes each person (Noble Prize). This small percentage is enough to make each person different and it makes identifying people a lot easier when its necessary. DNA not only serves to test relationships between people it also helps in criminal cases. DNA testing in criminal cases has not been around for many years if fact it was not until the early 1990s when the use of DNA testing for criminal cases was approved and made available. By comparing the DNA of a suspect and that found in the crime scene a person can either be convicted of a crime or they can be exonerated. This method of testing gained more publicity in the 1984 case of Kirk Noble Bloodsworth a man who had been convicted of the rape and first degree murder of a nine year old girl in Maryland. His case was a milestone in the criminal justice system since it involved the use of new technology and it also raised the question of how many people had been wrongly incarcerated for a crime they did not commit.

    Many things have impacted both the Science and Medical fields of study. Electrophoresis and DNA Sequencing are two of these things. Together they have simultaneously impacted both of these fields. On one hand, there is Electrophoresis. Electrophoresis is a specific method of separating molecules by their size through the application of an electric field. It causes molecules to migrate at a rate and distance dependent on their size. On the other hand, there is DNA Sequencing. DNA Sequencing is a technique used to determine the exact sequence of bases

    The molecule consisted of a double helix with phosphates, deoxyribose sugar molecules, and nitrogenous bases. If the spirals were split, the DNA could replicate, which explained why genes were transferred from parents to their children. Additionally, the order of compounds on the DNA indicated that there was a unique ‘code’ on each strand. Watson and Crick believed that this ‘code’ was translated into specific proteins. , ,

  • The Creation Of DNA By James Watson And Francis Crick

    1586 Words  | 4 Pages

    In April of 1953, James Watson and Francis Crick published a game changing paper. It would blow the mind of the scientific community and reshape the entire landscape of science. DNA, fully knows as Deoxyribonucleic Acid is the molecule that all genes are made of. Though it is a relatively new term with regard to the age of science, the story of DNA and the path to its discovery covers a much broader timeframe and had many more contributors than James Watson and Francis Crick. After reading the paper the audience should have a better understanding of what DNA is, the most important experiments that contributed to its ultimate discovery and the names and contributions of the lesser-known scientists that helped Watson and Crick turn their idea

    Deoxyribo Nucleic Acid (DNA) is a chromosome found in the nucleus of a cell, which is a double-stranded helix (similar to a twisted ladder). DNA is made up of four bases called adenine (A), thymine (T), guanine (G), and cytosine (C), that is always based in pairs of A with T and G with C. The four bases of A, C, G, and T were discovered by Phoebus Levene in 1929, which linked it to the string of nucleotide units through phosphate-sugar-base (groups). As mention in Ananya Mandal research paper, Levene thought the chain connection with the bases is repeated in a fix order that make up the DNA molecu...

    It is important to note that genes themselves do not cause disease genetic disorders are caused by mutations that make a gene function improperly. For example, when people say that someone has the cystic fibrosis gene, they are usually referring to a mutated version of the Cystic Fibrosis Transmembrane Conductance Regulator gene, which causes the disease. All people, including those without cystic fibrosis, have a version of the Cystic Fibrosis Transmembrane Conductance Regulator gene.

    DNA in forensic science has been around for a long time. DNA has had help in solving almost every crime committed. There have been a lot of crimes where people are raped or murdered and the person who did it runs free. Scientists can collect the littlest item they see at the scene, such as a cigarette butt or coffee cup and check it for DNA. People have spent years in jail for a crime they didn’t commit till DNA testing came into effect. People are getting out of jail after 20 years for a crime they didn’t commit, cause of the DNA testing. DNA has helped medical researchers develop vaccines for disease causing microbe. DNA has become a standard tool of forensics in many murders and rapes.

  • genetic mutations

    1467 Words  | 3 Pages

    A genetic mutation is a permanent change in the sequence of the DNA that makes up a gene. A mutation of these sorts can be caused by either inheritance from the parent or caused sometime during the life of someone. The mutation that has been inherited is called a germline mutation. Germline mutations affect virtually the entire body, and they seem to be present in every cell. A somatic mutation, or one that is caused in the DNA of a single cell sometime during the life, can be caused by an environmental factor or a wrong bonding in the DNA molecule. These cannot be passed down to the next generation of children because they occur in a specific cell as opposed to in a reproductive cell. Some mutations occur in the embryo as it is growing. These may occur during cell division, and some of the cells may or may not inherit this mutation. Some mutations are extremely rare, and others are incredibly common. Those that occur in more than one percent across a population are considered polymorphisms. Polymorphisms are considered normal variations in DNA, and they are known to cause simple changes such as variations in blood types and hair color. Although these are not typically fatal, they can influence the creation of some disorders (Lister Hill National Center for Biomedical Communications, U.S. National Library of Medicine, National Institutes of Health, Department of Health and Human Services, USA.gov, 2013).

    Changes in the genes contribute to the differences among people all over the world. Mutation is the change of the nucleotide sequence of the genome in an individual. It occurred in one individual and then it passed down that mutated gene to that individual’s offspring. Regions within DNA can be surveyed by examined the sections called makers, which distributed across a large portion of a chromosome. As each marker has a specific difference, and that is called an allele.
