Verified step by step guidance1
Understand the definitions of each term provided: A chromosome is a structure made of DNA and proteins that contains many genes; a nucleotide is the basic building block of DNA and RNA; a ribosome is a cellular structure that synthesizes proteins.
Recall that a gene is specifically defined as a segment of DNA that contains the instructions to produce a particular trait or protein.
Recognize that the question asks for the term that best fits the description 'a segment of DNA that codes for a trait,' which aligns with the definition of a gene.
Eliminate other options based on their definitions: chromosomes are larger structures containing many genes, nucleotides are individual units, and ribosomes are involved in protein synthesis but are not DNA segments.
Conclude that the correct term describing 'a segment of DNA that codes for a trait' is a gene.
