Verified step by step guidance1
Understand the definition of a gene in genetics: A gene is a fundamental unit of heredity in living organisms.
Recall that genes are segments of DNA, which contain the instructions to produce functional products, typically proteins or RNA molecules.
Eliminate options that do not fit this definition: a gene is not an entire chromosome, nor is it a lipid molecule or a protein itself.
Recognize that a gene specifically refers to a segment of DNA that encodes a functional product, such as a protein or RNA.
Conclude that the correct description of a gene is 'a segment of DNA that encodes a functional product.'
