  DNA Structure Experiments Proving DNA as Genetic Material Introduction DNA (Deoxyribonucleic Acid) is the hereditary material in almost all living organisms. It stores genetic information and directs the synthesis of proteins, making it the blueprint of life. Key Features Double Helix : DNA consists of two polynucleotide chains coiled around each other, forming a right-handed helix. Nucleotides : Each nucleotide is made of three components: A sugar (deoxyribose) A phosphate group A nitrogenous base (Adenine, Thymine, Cytosine, Guanine) Complementary Base Pairing : Adenine (A) pairs with Thymine (T) via two hydrogen bonds. Guanine (G) pairs with Cytosine (C) via three hydrogen bonds. Strand Orientation DNA strands are antiparallel : one runs in the 5′ → 3′ direction, the other in the 3′ → 5′ direction. This orientation is essential for replication and transcription. Stability and Packaging The sugar-phosphate backbone provides structural stability. DNA is tightly packed into ...

  Eli Lilly and the Story of Insulin: Introduction The discovery and commercialization of insulin stand as one of the most important milestones in medical history. Before insulin, diabetes was often a death sentence. The collaboration between Canadian researchers and Eli Lilly & Company changed that forever, making insulin widely available and saving millions of lives. The Early Days of Insulin In 1921, Canadian scientists Frederick Banting and Charles Best discovered insulin. Eli Lilly partnered with them to mass-produce insulin , becoming the first pharmaceutical company to do so in 1923. The initial product, Iletin , was derived from animal pancreases (cattle and pigs). While effective, it had limitations in purity and consistency. Advances in Biotechnology By the late 20th century, Eli Lilly pioneered the use of recombinant DNA technology to produce biosynthetic human insulin. This breakthrough eliminated the need for animal sources, reduced allergic reactions, and improve...

  Bacillus thuringiensis In the search for sustainable alternatives to chemical pesticides, Bacillus thuringiensis (Bt) stands out as one of biotechnology’s most impactful discoveries. This naturally occurring, soil-dwelling bacterium has transformed modern agriculture by offering a targeted, environmentally responsible approach to pest control. What Is Bacillus thuringiensis ? Bacillus thuringiensis is a Gram-positive bacterium known for its ability to produce crystalline (Cry) proteins during sporulation. These proteins are toxic to specific insect larvae, particularly those in the orders Lepidoptera, Coleoptera, and Diptera. When ingested, Cry proteins bind to receptors in the insect gut, creating pores that disrupt digestion and ultimately lead to the insect’s death. What makes Bt unique is its specificity. The toxins affect only targeted pests and are harmless to humans, animals, and most beneficial insects, making Bt a powerful tool in sustainable agriculture. Bt in Bi...

  Biogas: Turning Waste into Renewable Energy Introduction As the world searches for sustainable energy solutions, biogas has emerged as a powerful alternative to fossil fuels. Produced from organic waste, biogas not only generates clean energy but also addresses waste management and environmental concerns. It represents a circular approach to energy production, where waste becomes a resource rather than a problem. What is Biogas? Biogas is a mixture of gases, primarily methane (CH₄) and carbon dioxide (CO₂), produced through the anaerobic digestion of organic matter. This process occurs when microorganisms break down biodegradable materials such as agricultural residues, food waste, sewage, and animal manure in the absence of oxygen. Typical composition of biogas: 50–70% methane 30–40% carbon dioxide Small amounts of hydrogen sulfide, nitrogen, and water vapor The methane content makes biogas a valuable fuel, comparable to natural gas. How Biogas is Produced Collection of Organic ...

  The Krebs Cycle Introduction Every living organism requires energy to survive, grow, and reproduce. At the cellular level, this energy is supplied in the form of ATP (adenosine triphosphate). One of the most important pathways for generating ATP is the Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle. This cycle lies at the heart of cellular respiration, linking the breakdown of carbohydrates, fats, and proteins to the production of energy. Where It Happens The Krebs cycle occurs in the mitochondrial matrix of eukaryotic cells. In prokaryotes, which lack mitochondria, it takes place in the cytoplasm. It is a central metabolic pathway, meaning it not only generates energy but also provides intermediates for biosynthesis. Steps of the Cycle The cycle begins after glycolysis, when glucose has been broken down into pyruvate. Pyruvate is converted into acetyl-CoA, which enters the Krebs cycle. The main steps are: Formation of Citrate: Acetyl-CoA c...
