In Animals:

1. Transgenic Animals: Produce human proteins in milk and semen, such as cattle and goats, with high-quality milk and required nutrients.
2. Enzyme Production: Transgenic goats produce enzymes for blood clotting.
3. Hormone Production: Rabbits secrete hormones for treating bone disorders.
4. Clotting Factors: Sheep produce human clotting factors.

In Medicine:

• Human Vaccines: Produced using microorganisms, e.g., hepatitis B vaccine for humans and foot-and-mouth disease vaccine for cattle.

In Plants:

• Pest Resistance: Genetically modified plants resist pests.
• Environmental Resilience: Plants withstand harsh conditions like drought.
• Extended Ripening: Tomatoes are engineered to stay fresh longer.
• Nutrient Enrichment: Plants such as soybeans and tomatoes are developed to contain higher levels of essential nutrients.
• High-Yield Crops: Rice enriched with vitamin A and iron.
• Biodegradable Plastics: Plants are used to produce chemicals for plastics, reducing soil pollution.
