Micheal Pollan’s "Playing God in the Garden" addresses the many unseen aspects of farming and the technologies that are being designed to make planting effortless and safe. Pollan discusses how New Leaf (the plant company which has created the new biotechnological seeds) advertises a safer and less expensive way of farming‚ while concealing the harmful aspects of its product. The idea of genetically altering organisms has always made me uncomfortable. When I began to read this article‚ I assumed

During my period of study here‚ I have taken courses like Biochemistry‚ Molecular Cell Biology‚ Microbiology‚ Immunology‚ Bioprocess principles and engineering‚ Bio and chemical thermodynamics‚ Enzyme engineering. These courses took me a step closer towards fulfillment of my goal of delving deeper into the world of ‘cloned Dollies’ and ‘Docile DNA’. The fascinations and promises held out by various areas in molecular biology‚ biochemistry and

Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

Guide to Profitable Investment in Pig Farming By Obinna Chima Before Miss Oyinlade Adetutu graduated from the University of Ibadan in 2005‚ she had already made up her mind not to go into the already saturated labour market. As a student of Agricultural Science‚ she had vowed to stick to her profession by investing in the sector in order to tap from the benefits that abound in it. Though she specialised in fisheries‚ she got to know about pig farming and became attracted to it because of the
