one organism to another
➢ Foundation of biotechnology transforming modern science
➢ Creates Genetically Modified Organisms (GMO) or Transgenic organisms
➢ Applications in health, agriculture, industry, environment
➢ Enhancing quality, productivity & sustainability

SCOPE IN AGRICULTURE
CropImprovement:
➢ Golden Rice — biofortified with Vitamin A for malnutrition prevention
➢ Disease-resistant plants — Tomato mosaic virus resistance
➢ Drought-resistant seeds — adapted for water-scarce regions
➢ Pest-resistant cabbage — scorpion tail gene kills caterpillars (safe for humans)
➢ Strawberry with antifreeze gene — prevents freezing, extends shelf life
➢ Bt Cotton — produces natural insecticide
➢ Benefits:
❑ Reduced chemical pesticide dependency
❑ Higher crop yields
❑ Food security & sustainability

SCOPE IN MEDICINEAND GENE THERAPY
➢ Pharmaceutical Production:
❑ Insulin production (pig/cow pancreas → bacterial fermentation)
❑ Vaccine synthesis
❑ Growth hormone for dwarfism treatment
➢ Gene Therapy Process:
❑ Bone marrow stem cells extracted from hip bone
❑ Vector carries therapeutic gene into stem cells
❑ Modified cells returned to patient (5 days later)
❑ Corrects genetic disease at cellular level

SCOPE IN ANIMALSCIENCE
➢ Livestock Engineering:
❑ High-milk breeds — Cows producing 20% more milk
❑ Leaner meat — Genetically modified pigs with reduced fat content
❑ Faster growth — Pigs, cows, fish engineered for rapid development
❑ Disease-free livestock — Improved health traits
➢ Research & Production:
❑ Transgenic animals — laboratory models for disease research
❑ Animal cloning — Dolly the Sheep (1996)
➢ Biopharming (Protein Production in Animals):
❑ Goats producing silk protein in milk → BiostEEL material (artificial ligaments, parachute cords)
➢ Xenotransplantation:
❑ Pig organs genetically modified for human transplants
