A length of DNA that is a unit of heredity and codes for one or more specific proteins is a?

Explanation:
Genes are specific lengths of DNA that carry the instructions to make a particular protein. This is what makes them the units of heredity passed from parents to offspring. A genome is the entire set of genetic material, a chromosome is a structure that holds many genes, and an allele is a variant form of a gene. So the description matches a gene.
