Process Identification Abstract Signs of the impending recall crisis began as early as 2006 when the National Highway Traffic Safety Administration (NHTSA) initiated an investigation into driver reports of “surging” in Toyota’s Camry models. This investigation was closed the next year declaring that there were no defects. Known in the industry for their quality and reliability‚ Toyota would silently recall almost nine million Toyota and Lexus models due to the sudden acceleration problems.

Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids‚ carbohydrates‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain

What are bacteria? Bacteria are very different from viruses. First of all‚ bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye. They are so small that the sizes of bacteria are measured in micrometers (10‚000 micrometers = 1 centimeter). By comparison‚ the head of a pin is about 1000 micrometers wide. Though more complex than a virus‚ the structure of a

over 99% of bacteria or antibiotics aren’t discovered. However‚ recently a new antibiotic called teixobactin was discovered. This antibiotic prevents the synthesis of a cell wall by binding to a motif of lipid II and lipid III molecules. The goal of this experiment was to discover how teixobactin interact with bacteria and how it is able to effectively kill pathogens. A device called the iChip was used to discover teixobactin. The iChip helped to isolate and grow uncultured bacteria. Multiple iChips

“Should we manipulate the DNA of bacteria?” This is a question that has no definite answer‚ but a limitless amount of controversy. Since DNA is the code within each and every cell that instructs them on how to function and bacteria are rapidly reproducing microbes‚ genetic engineering is something to be considered. In fact‚ Bacteria were the first organisms to be genetically engineered. Modifying or manipulating the DNA of microbes and bacteria should continue to be allowed because it can be used

experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments of DNA

Mystery bacterium I would not say science is storybook fun‚ but who knew it become a mystery. Trying to find out what was in our number seven vial would become a battle we were willing to take on. As I began the test of deciding if our little bacteria friend was gram positive or negative‚ Jordan my science teammate‚ was putting together a smear plate. In as little as ten minutes we had discovered by the pink oval shapes we were observing‚ our microbe friend was a gram negative rod. We had narrowed

Introduction The purpose of this experiment is to see how much bacteria can and will grow in common places in a typical high school. Common places can mean many things‚ including anything from water fountain spouts to computer keyboards. Such objects can hold up to 2‚700‚000 colony forming units per square inch (or CFU/in sq)(NSF). A colony forming unit is the unit used to find an estimate of the number of cells of a bacteria. This unit of measurement is commonly utilized in the subject of microbiology
