Verified step by step guidance1
Understand that DNA is composed of segments that carry genetic information.
Recognize that a 'gene' is the specific segment of DNA that contains the instructions to code for a particular trait.
Differentiate between related terms: a 'codon' is a sequence of three nucleotides that codes for an amino acid, a 'chromosome' is a large structure made of DNA and proteins containing many genes, and an 'allele' is a variant form of a gene.
Conclude that the correct term for a DNA segment coding for a trait is a 'gene'.
Remember that genes are the fundamental units of heredity responsible for traits passed from parents to offspring.
