A DNA section that codes for a protein and thus determines a trait is called what?

Explanation:
A gene is a specific segment of DNA that contains the instructions to build a protein. That protein carries out functions in the cell and helps determine a trait, like color or shape. A chromosome is a larger structure that holds many genes, an allele is a version of a gene, and a protein is the product made from the gene’s instructions. So the DNA section that codes for a protein and influences a trait is a gene.
