How Does Structure and Replication of Bacterial Cells Work?

Bacterial cells are like tiny, super-efficient factories that can copy themselves to make more bacteria.

Imagine you have a copy machine in your classroom, it takes a paper and makes an exact copy of it. Bacteria work kind of like that copy machine, but inside their own factory.

Bacterial cells are simple, like a tiny lego block. They have a skin called a cell wall that protects them, and inside is jelly-like stuff (called cytoplasm) where all the action happens. In this jelly, there’s a special instruction book, the DNA, which tells the bacteria what to do.

When it's time for a bacterial cell to make more of itself, it starts by making a copy of its instruction book (DNA). Then it splits in half, like your favorite playdough snake splitting into two snakes. Each new bacteria gets one copy of the instruction book and becomes a full factory on its own.

This copying process is super fast, sometimes they can make copies every 20 minutes! That’s why you can get sick really quickly from something like bacteria in food.
