Question

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?
A.Some kinds of atoms that are found in DNA must be left out of the models.
B.DNA has so many atoms that the size and cost of a model could be too great.
C.It is impossible to distinguish different kinds of atoms with models.
D.The chemical bonds between the atoms in DNA must be part of the models.

Answer 1

ball-and-stick models are unrealistic depictions of molecules; they completely ignore what chemists know from quantum mechanics about the nature of matter at the subatomic level. Nonetheless, 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.
