  • Genetic Engineering In Medicine

    genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism. Genetic engineering has applications in medicine, research, industry and agriculture and can be used on a wide…

  • Genetically Modified Foods: Pros And Cons

    Genetically Modified Foods refers to plants which are produced by both animal and human consumption through the use of the modern molecular biology techniques. The plants have been changed in the laboratory so as to enhance the preferred features like better nutritional content or raise resistance to herbicides (Arvanitoyannis and Krystallis, 2005). The modification of the desired features has traditionally been carried out through breeding, but some of the breeding methods like conventional…

  • Potato Dextrose Agar Essay

    4.1 Maintenance and sub-culturing of endophytic fungi The cultures were procured from already maintained repository in laboratory. The maintenance of the cultures involved preparation of Potato dextrose agar (PDA) plates, sub culturing of cultures and long term preservation. 4.1.1 Preparation of PDA (Potato dextrose agar) plates 39g of PDA was dissolved in 1000 ml double distilled water, stirred to mix properly and was transferred into 250 ml Erlenmeyer flasks and autoclaved at 121˚C at 15…

  • DNA Fingerprinting

    solution is added to the cup and the amount added should be equal to the volume of the sample mixture, however once the DNA started to precipitate in the solution I stopped adding the ethanol. The DNA should be visible as a transparent white floating mass within the solution and it can be observed, removed, touched and…

  • Fluid Mechanics: Non-Newtonian And Fluid Mechanics

    viscosity to decrease, so the fluid gets "thinner" (this is present in non-drip paints). There are many types of non-Newtonian fluids, as they are defined to be something that fails to obey a specific (particular) property i.e., most fluids with long molecular chains can react in a non-Newtonian way. The constant of proportionality between the velocity gradient and the viscous stress tensor is known as the…

  • Pancreatic Adenosquamous Carcinoma Case Study 1

    Boyd, Benarroch-Gampel et al. 2012). A major hindrance towards development of therapies against pancreatic ASC is that no unique molecular signature has been identified for this class of pancreatic tumors. Although KRAS and TP53 are altered in pancreatic ASC (Brody, Costantino et al. 2009), the same genes are also abnormal in other forms of pancreatic cancer. The molecular mechanism that promotes pancreatic adenosquamous carcinoma is unknown. The main objective of this proposal is to identify…

  • Polyploidy Essay

    Polyploidy in plants play a major role in evolutionary and genetic studies. Polyploidy is characterized by the presence of multiple sets of genomes in the same organism. It is one of the major causes of speciation; thus, is it plays a major evolutionary role in angiosperm development. Its genome undergoes remarkable changes in function and structure through genetic and epigenetic changes. Epigenetic changes are mediated by RNA and chromatic remodeling and occur vie regulatory pathways. Genetic…

  • Unknown Plasmid Lab Report

    Identifying an Unknown Plasmid Through the Process of Gel Electrophoresis Introduction: Biotechnology requires certain techniques and methods that help identify plasmids, which can be used for forensics, DNA fingerprinting, etc. In this class, each lab focused on teaching the process of using the correct techniques used to identify a plasmid. Plasmids are pieces of DNA that are circular and relatively smaller than chromosomes. They aren’t important in the sense that they don’t carry out…

  • Gene Editing Ethics

    Recently, scientists in the UK have been given the green light to start research on editing the DNA of a human embryo. The ability to unzip defective genes and replace them with nondefective copies of genes has sparked a huge debate on the ethics of human gene editing. In this paper, I will briefly explore the procedure of gene modification using the editing tool CRISPIR/Cas 9, the exciting possibilities of successfully using this method, and debate several ethical concerns that have arisen due…

  • Crick's Theory Of Dna

    1) A. In 1947 Francis Crick began working with Max Perutz at the Cavendish Laboratory in Cambridge. He began working on a new sector of the Laboratory where X-ray crystallography was being used in order to study protein structure. Crick's thesis project at the university was on X-ray diffraction of proteins. Crick then met John Watson and together they solved the structure of DNA using available X-ray data at the time and model building. After discovering the double helix model, Crick and…
