Tightly coiled DNA forms a structure called a chromosome.

A DNA molecule is divided up into functional units called genes.

The flower color gene provides instructions for a protein that helps create the phenotype, or outward expression of a trait.

In most cases, the functional product of a gene is called a protein.
