Here's the breakdown:

* Cells are the basic building blocks of all living organisms. They contain DNA within them.

* DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for building and maintaining an organism.

Think of it like this:

* A house is made up of many bricks.

* DNA is like the blueprint for the house, containing all the instructions for building it.

* Cells are like the bricks themselves, using the DNA blueprint to create the organism.

So, DNA is a molecule found inside of cells, not the other way around.
