    DNA Extraction In extracting chromatin from the cells of wheat germ there are seven steps to follow. The optimal cell to use would be the polyploidal eukaryotic. Eukaryotes have nucleus membrane-bound organelles, while prokaryotic does not. The polyploidal eukaryotic cell has DNA that is held in the nucleus while the prokaryote has DNA that floats freely around the cell. The DNA of eukaryotes is more complex and extensive than the other. Prokaryote is a bacterial cell that

  • Caffeine Extraction Experiment

    1054 Words  | 3 Pages

    The objective of this experiment was to perform extraction. This is a separation and purification technique, based on different solubility of compounds in immiscible solvent mixtures. Extraction is conducted by shaking the solution with the solvent, until two layers are formed. One layer can then be separated from the other. If the separation does not happen in one try, multiple attempts may be needed. The experiment was conducted in three parts: Part A of the experiment consisted of extracting

  • Acid Base Extraction

    Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid/base extraction involves carrying out simple acid/base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substances

  • Asphalt Extraction Essay

    703 Words  | 2 Pages

    Extraction of Asphalt from a mix is a common practice in the asphalt laboratories. The extracted asphalt is used for characterization in the laboratories to ensure quality, performance and research. ASTM D2172 is the most accepted procedure for asphalt extraction. This procedure includes five methods such as Method A the centrifuge extraction, Method B the Reflux extraction, Method C first variation of the Reflux method, Method D the second variation of Reflux method and Method E the vacuum extraction

  • Extraction Of Iron Essay

    651 Words  | 2 Pages

    Extraction Of Iron Iron, perhaps the most important element to all civilization is also one of earth's most abundant. Like the majority of metal ores, iron ores are not pure compounds. Rather, most iron ore compounds are polluted with sand, rock and silica. The process of extracting iron involves a number of steps. The first step to concentrate the iron ore and remove its contents of silica. To further remove any existing impurities, a complex process takes

    Acme Minerals Extraction Company A long time ago, work used to be assigned only to one person and that person was in charge of doing only that task. Then, with the new technology innovations, we start seeing how companies started to trained some employees to be what they usually called “multi-tasking employees”. Since technology kept changing and became more advanced companies realized that having “multi-tasking employees” was not enough to satisfy the market demands and the production problems

  • Liquid Liquid Extraction

    2140 Words  | 5 Pages

    Liquid Liquid Extraction We were asked to extract benzoic acid from a kerosene-benzoic acid mixture. This was to be done using the stirred liquid-liquid extraction column in the senior laboratory. Fresh water was used as the continuous phase in the extraction. We were asked to measure the benzoic acid concentrations of the feed, raffinate, and extract streams. These measurements were to be made at several different steady-states. The number of theoretical stages and the height of the theoretical

  • A Summary Of Acid-Base Extraction To Isolate Eugenol

    783 Words  | 2 Pages

    Performing this experiment, we used the technique called Acid-Base extraction to isolate Eugenol, which is one of the main ingredients of clove oil. Acid-Base extraction is the most efficient method for isolating organic component; it is efficient because it purifies the acid and base mixture based on their chemical identities. We have seen throughout this experiment that acid and base play an important role, when it comes to solubility in water. Our basic knowledge of acid and base is acid is a

  • Extraction Of Sulfur Extraction

    3021 Words  | 7 Pages

    Sulfur Extraction Sulfur extraction is what industries use to extract sulfur that is to be used for applications within many processes. From this companies can use the sulfur to produce sulfuric acid, sulfur dioxide, and sulfur trioxide to use in their processes. Industries use two methods because it is the most common as well as the most reliable way to recover sulfur from the earth. There are many ways to extract sulfur but the two most common ways are the Frasch process and the extraction through

  • Extraction Of Metal Extraction

    1641 Words  | 4 Pages

    ores usually contain a very small proportion of the targeted metal, e.g. 1~2% for copper and 0.05% for uranium(Hester et al., 1994). As a result, large amounts of impurities are separated during metal extraction. These impurities are waste and need to be safely disposed of. Mining and metal extraction procedures produce waste at different stages. Tailings are generated during preliminary stages of ore beneficiation, and hydrometallurgical wastes are generated during metal extraction.However, the composition

  • Oil Extraction Essay

    920 Words  | 2 Pages

    There are three major methods in extraction of edible oil from plants and fruits. The first major method is by solvent extraction with organic solvent. This method is mostly suitable for plants with low fat content. Since every species of plant consists of different composition, hence the modification of this method is needed based on different plants. Firstly, the traditional and conventional solvent extraction has been widely and commonly used for many plants. However, some studies show this method
