Verified step by step guidance

Step 1: Understand the definition of a gene in genetics. A gene is a fundamental unit of heredity that carries the instructions for making molecules essential for life.

Step 2: Recognize that genes are made up of DNA, which contains sequences that encode information for producing proteins or functional RNA molecules.

Step 3: Differentiate genes from other biological molecules or structures, such as carbohydrates, cells, or proteins themselves, which are not genes but may be related to gene function or expression.

Step 4: Recall that proteins are the products of gene expression, not the genes themselves; genes provide the code to synthesize these proteins.

Step 5: Conclude that the best description of a gene is 'a segment of DNA that encodes information for the synthesis of a specific protein or functional RNA.'
