Genetic Engineering
📋 What it is
Genetic engineering directly edits an organism’s DNA to add, remove, or change genes.
🗣️ Coach says
Where biotech USES living things, genetic engineering directly EDITS their DNA — adding, removing, or changing genes. Modern tools (like CRISPR) act like precise molecular scissors. It can cure genetic diseases or improve crops, and because it changes life itself, it demands careful ethics.
🧠 Memory hook
Genetic engineering = directly editing DNA. Powerful, precise, and ethically weighty.
😂 Giggle
Why is DNA the ultimate instruction manual?
Because it's got every detail coded right in!
😲 Whoa!
CRISPR gene-editing is so precise it can change a SINGLE letter of DNA out of billions — like fixing one typo in a library of books.
✅ Quick check: How is genetic engineering different from ordinary breeding?
Say your answer out loud first — then reveal.
It directly edits the DNA (adding/changing specific genes), rather than just selecting parents and hoping for traits.
Engineering targets genes precisely; breeding selects from natural variation.

Imagine editing ONE gene in a plant to resist drought. What’s one benefit and one “should we?” worry?
