DNA holds the instructions that a creature requires to develop, live, and reproduce. DNA sequences must be turned into signals that can be utilized to build proteins, which are the complex molecules that do the majority of the work in our bodies, in order to perform these activities.
A gene is any DNA sequence that carries instructions for making a protein. In humans, the size of a gene can range from roughly 1,000 bases to 1 million bases. Genes account for just roughly 1% of the DNA sequence. Outside of this 1%, DNA sequences have a role in determining when, how, and how much protein is produced.
