Biologists use ball-and-stick models to study complex molecules by representing atoms with balls and bonds with sticks. dna is a biological molecule that contains millions of atoms.

what is a limitation of using a ball-and-stick model for dna?

The question is asking to states what could be the limitation of using a ball and stick model for DNA and base on my research, I would say that they are simple, easy to draw and offer a wealth of insights into molecular structure and properties in a way that's easy to visualize and understand.
