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

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

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

a molecular sieve is created such that the distance traveled in the gel toward the anode by any DNA fragment (all of which carry negatively charged phosphate groups in the presence of a basic buffer) is inversely proportional to its molecular weight. Further‚ such distance traveled has a linear relationship with the log of such fragment’s molecular weight. Since DNA consists solely of deoxyribonucleotides that differ only by their bases and each base pair has approximately the same molecular weight

opposed to those performed ten years ago and analyse its future implications. The thrust of research while studying biology at a molecular level initially was focused specifically on the genomes of various organisms. As scientists discovered the intricacies of genes and their functionalities‚ the attention was soon drawn towards the end result of the central dogma of molecular biology‚ namely‚ the proteins‚ produced through translation of RNAs. Therefore‚ to study the proteins produced in an organism
