What Is Genetic Engineering?
Think of genetic engineering as nature's copy-and-paste function - scientists literally cut out useful genes from one organism and insert them into another. It's like giving organisms new superpowers by borrowing DNA from other living things.
The process works by using special enzymes to slice out the target gene, then inserting it into a bacterial plasmid (a small ring of DNA). This plasmid acts as a delivery vehicle, carrying the new gene into the cells of the organism you want to modify.
Modern applications are everywhere around you. Your food might come from crops that resist diseases or produce higher yields. Some fruits stay fresh longer thanks to genetic modifications. Even livestock can be engineered to produce more nutritious milk.
Quick Tip: The key is doing this modification at the earliest stage of development, so every single cell in the organism carries the new trait.
