Praxis 5005 Practice Test Practice Question
Genetic instructions that are passed from generation to generation are carried by which of the following organic molecules?
Correct Answer: C
Rationale: Genetic instructions are encoded in nucleic acids, specifically DNA and RNA, which store and transmit hereditary information. Proteins (A) are essential for various cellular functions but do not carry genetic information. Carbohydrates (B) primarily serve as energy sources and structural components, lacking a role in genetic transmission. Lipids (D) are involved in cell membrane structure and energy storage, but they do not convey genetic instructions. Thus, nucleic acids are the key molecules responsible for passing genetic information across generations.
