DNA is made up of two long polynucleotide chains wound together.

Location 

Gene is located on a chromosome. 

DNA is located within the nucleus of a cell. 

Role

Gene determines the traits of an organism.

DNA determines multiple functions including gene regulation.

Function

A gene is coded with heredity information.

DNA encodes the genetic instructions.
