original identification of DNA was by a Swiss chemist named Friedrich Miescher. In 1869, Miescher labeled a “nuclein” inside a human white blood cells nucleus. His term was later changed to nucleic acid which eventually leads to the term we know today at deoxyribonucleic acid (DNA) (Pray, 2008). B. DNA is located in the nucleus of the cell. Inside each nucleus of a cell is two meters of DNA. The genetic makeup of DNA consists of chemical building blocks of nucleotides. Nucleotides are made up of three
therapy, genetic modification, genetic enhancement, and cloning. Gene therapy and genetic enhancement use similar processes to alter specific portions of the DNA, whereas cloning has a more specific method which is different in relation. The basic process of genetic modification will be used as an example to illustrate the technical aspects of research areas like gene therapy and genetic enhancement. In addition to genetic modification techniques, cloning has specific applications in animals. A specific
oxygen in a process called aerobic respiration and mitochondria enable cells to produce 15 times more ATP than they could otherwise. The number of mitochondria present in a cell depends upon the metabolic requirements of that cell, and may range from a single large mitochondrion to thousands of them. mitochondria are different from most organelles because they have their own DNA and reproduce independently. In most animal species, mitochondria appear to be inherited through the
DNA Extraction Being able to gather large amounts of DNA together has many potential advantages. It is possible to collect this DNA and use it for purposes such as research for medical uses. To extract the DNA from cells, you need to follow a series of steps which will result in the separation of DNA from other parts of the cell. After following the procedure, you will be left with a stringlike mass of DNA that can be easily examined. To begin, you will need 1 gram of raw wheat germ, 1 ml of liquid
things including both eukaryotic and prokaryotic organisms. DNA is tightly packaged in the chromosomes to start DNA replication. During this process, DNA unwinds so that it can be duplicated. DNA can be extracted from strawberries which can also explain how DNA can be used for medicinal purposes as well as explaining how DNA extraction originated. The extraction of DNA was first discovered by Swiss physician Friedrich Miescher in 1869 while working in his lab. Friedrich attended University of Tubingen

cloning includes the attempts required to create a viable egg. The stability of the egg is poor and may require hundreds or attempts before success is attained. Also, the morality of therapeutic cloning had received controversial backlash because the extraction of stem cells from the embryo results in the destruction of the embryo being used. Some argue that the pros outweigh the cons with regards to treating disease whilst others have likened the destruction to abortion (Murnaghan, 2017). Pluripotent
Mining of tar sands is quite tough and hard to do. The sands cannot be pumped in their natural state. It must be mined through open pit mining techniques. After mining the sands are transported to and extraction plant where a hot water process separates the bitumen from sand, water and minerals. This process releases the bitumen from the oil sands and causes tiny air bubbles to attach to the bitumen droplets that float to the top of the separation vessel, where the bitumen can be skimmed off. (Oil Shale
the toothpaste we use to brush our teeth is made of abrasives, fluoride, and detergents. It is a very simple fact that chemistry plays an important role in every person’s daily activities from the moment we’re born. The role of chemistry usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which
Marlon Aguilar Mrs. Kline Period 7 4 April 2017 Title Despite the occasional risks and challenges that may arise in the process, genetic engineering provides more benefits that far outweigh the harms. Genetic engineering, and genetics in general, is a subject unfamiliar to the general public because not only has it not had much exposure to people outside of the scientific world, but it is also extremely complex and still has several applications yet to be found. In short, genetic engineering is
