Verified step by step guidance1
Understand that DNA is organized into segments, each with specific functions related to heredity and traits.
Recognize that a 'gene' is the fundamental unit of heredity, defined as a section of DNA that contains the instructions to produce a specific trait or protein.
Differentiate between the options: an 'allele' is a variant form of a gene, a 'chromosome' is a larger structure made of DNA and proteins containing many genes, and a 'codon' is a sequence of three nucleotides that codes for an amino acid.
Conclude that the term describing a section of DNA that codes for a trait is a 'gene'.
Remember that genes are the key units responsible for inherited traits, making 'gene' the correct answer.
