  • Antibiotic Sensitivity Advantages And Disadvantages

    Antibiotic sensitivity is the susceptibility of bacteria to antibiotics. Susceptibility can vary within bacteria of the same species due to different strains; with some strains being more resistant than others. Antimicrobial resistance is the ability of a microorganism to survive and multiply in the presence of an antimicrobial agent that would normally inhibit or kill this species of microorganism. Antibiotic susceptibility tests are done in order to determine, which specific antimicrobials…

  • Gene Regulation In Biotechnology

    Today in the 21st century our gene technology is continually developing. New projects and discoveries are being made on a daily basis. Gene technology provides humans the opportunity to improve human and animal health, to create a safer and more sustainable food resources, and generate fortune for Australia. Gene technology is “where the genetic material of living things is deliberately altered to enhance or remove a particular trait and allow the organism to perform new functions” (Environment…

  • Genetic Therapy: The Limitations Of Gene Therapy

    carry various instructions. Inside of our DNA, there is a unique chemical code, which determines our growth, development, and health. This specific code is derived by four nucleotide bases that conform the DNA. These are called, adenine, cytosine, guanine, and thymine and are often represented as A, C, G, and T. In 1990, the Human Genome Project was conducted by the National Institutes of Health, and the US Department of Energy. This project allowed the understanding of the human genome…

  • Science Matters Achieving Scientific Literacy Summary

    Science Matters: Achieving Scientific Literacy Robert M. Hazen and James Trefil wanted to write a book a book that explained the fundamentals of science without being too obscure or specialized. Science Matters : Achieving Scientific Literacy is a book for the general reader that is informative enough to be a popular textbook for introductory courses in high school and college, and yet well-written enough to appeal to general readers uncomfortable with complicated mathematics. Anyone can…

  • DNA In Forensic Science

    components are constant in all persons and, therefore, biologists today utilize the nitrogenous base component since it helps in distinguishing different individuals. Indeed, this base is responsible for nucleotides that contain; cytonise, adenine, guanine or even thymine whose combination determines the exact coding capacity and function of the DNA as applied in forensic science. Today, DNA in forensic science is…

  • Gene Technology

    technology. DNA (deoxyribonucleic acid) is a macromolecule recognized as a nucleic acid. Which is formed like a curled double helix and is made of a long thread of varying sugars and phosphate groups, adjacent with nitrogenous keys (adenine, thymine, guanine and cytosine). It 's arranged into composition called chromosomes and contained inside the nucleus of cells. DNA holds…

  • Biological Macromolecules Research Paper

    Lesson 5: Structures, Functions and Roles of Biological Molecules and Enzyme Activity in Metabolism Biological Molecules/Macromolecules Plants produce their own food through photosynthesis. They manufacture mainly carbohydrates (glucose) as a source of food of many higher organisms in the food chain. It is one of the many biological molecules present in plants and needed by animals. Biological molecules are macromolecules composed of many monomers (polymer) connected through a covalent bond…

  • Nucleus Research Paper

    Nucleus In each cell, there is one nucleus. It is in the center of the cell, and takes up about ten percent of the cell’s volume. It is a large, oval-shaped structure bound by a double membrane called the nuclear envelope. Inside the nucleus, are organelles called nucleoli, which assemble RNA and synthesize ribosomal subunits. Throughout the inside of the nucleus, is a substance called the nucleoplasm, which suspends the nucleus’ structures. The nucleus controls the activities of the cell to…

  • Muckle-Wells Syndrome

    codon, and depending on where it is in the normal sequence of amino acids, it can severely alter the protein produced [16]. One mutation that has been shown to cause this defect on the NLRP3 gene is the p.D303N mutation. This mutation causes a G907A (Guanine to Adenine) transition on the DNA. This point mutation changes only one amino acid aspartic acid into asparagine in the peptide chain [17]. This is the most common mutation that causes…

  • Plasminogen Activator Inhibitor-1: An Experimental Study

    PAI-1 is associated with the impairment of vascular wall and endothelial dysfunction. (4).Human PAI-1 gene is located at chromosome 7q22, and various genetic polymorphism have been identified in its promoter region (4). A common insertion/deletion of guanine have been seen in this region (3). The deletion of the allele (4G) is associated with increased PAI-1 plasma level due to inability of transcriptional repressor protein for binding to this polymorphic sequence (5). C - reactive protein (CRP)…
