Verified step by step guidance1
Understand the definitions of each term: A 'codon' is a sequence of three nucleotides that codes for a specific amino acid during protein synthesis.
An 'allele' is a variant form of a gene that can result in different traits.
A 'chromosome' is a long DNA molecule that contains many genes and regulatory elements.
A 'gene' is a specific sequence of DNA that codes for a protein and thus determines a particular trait.
Therefore, identify that the term describing a DNA sequence coding for a protein and determining a trait is 'gene'.
