GM Crops: Benefits and Concerns

Benefits	Concerns
Higher crop yields Pest/disease resistance Vitamin enrichment Less pesticide use	Unknown long-term effects Could affect wild populations Biodiversity concerns Ethical issues

Visual: Genetic Engineering Process

Genetic engineering diagram showing the step-by-step process: identify gene, cut with restriction enzymes, insert into plasmid vector with ligase, transform bacteria, bacteria multiply, and harvest protein product like insulin.

Remember: Cut gene (restriction enzyme) → Insert into vector/plasmid (ligase) → Transform bacteria → Bacteria multiply → Harvest product
