Verified step by step guidance1
Understand that DNA is composed of many segments, each with a specific function related to heredity and traits.
Recall that a chromosome is a large structure made of DNA and proteins, containing many genes, but it is not the term for a single segment coding for a trait.
Recognize that a nucleotide is the basic building block of DNA, consisting of a sugar, phosphate, and nitrogenous base, but it does not code for traits by itself.
Know that an allele is a variant form of a gene, representing different versions of the same gene, but not the gene itself.
Identify that the correct term for a segment of DNA that codes for a specific trait is a gene.
