Verified step by step guidance1
Understand that a gene is a fundamental unit of heredity in living organisms.
Recognize that a gene is a sequence of DNA that contains the necessary information to produce a functional product, which can be either an RNA molecule or a protein.
Differentiate between the options given: an RNA molecule transcribed from DNA is a product of gene expression, not the gene itself.
Identify that a stretch of DNA that can be transcribed refers to the process of gene expression but does not define a gene.
Conclude that the best definition of a gene is a sequence of DNA that encodes a product like an RNA or a protein, as it encompasses the function and purpose of a gene in biological systems.
